With this molality calculator you can quickly calculate the molality - one way of measuring the concentration of a solute in a solution not to be confused with molarity. Simply type the number of moles of your solute substance and mass of the solvent and the tool will calculate the molality.

If you don't know how many moles of a substrate you have, use the advanced mode to calculate it with the use of mass and molar mass of the compound. Are you still unsure what's the molality definition, its units and formula - or simply how to calculate molality step by step?

Keep reading and you'll find the answer! Molality, also called molal concentration, is defined as the amount of substance of solute, divided by the mass of the solvent m solvent :.

Molarity and molality are similar concepts - both are measures of concentration of a solution. However, there is one main difference between those terms: molarity is expressed as the amount of substance per unit volume of solutionwhereas molality defines the concentration as the amount of substance per unit mass of the solvent. We've put all most important differences between those two terms into a short molarity vs molality table:.

Acid base titration calculations help you identify properties such as pH of a solution during an experiment, or what an unknown solution is when doing fieldwork. By using a solution with a known molarity and a colour indicator, we measure how much of the solution is required to neutralise the unknown solution, indicated by a change in the indicator, which we can use to work out information about the unknown solution.

Have a look at our neutralisation and molarity calculators as well! When doing a titration, we usually have a solution with a known volume but unknown molarity the analyteto which a colour indicator e.

The indicator will change colour when this ratio governed by its titration curve is achieved. By adding either an acid or a base with a known molarity the titrant and measuring how much is needed to cause this change, we can work out the molarity of the unknown, using the equation below:.

A titration curve is a plot of the concentration of the analyte at a given point in the experiment usually pH in an acid base titration vs. When working with a strong acid and a strong base, the curve around the equivalence point will be relatively steep and smooth. This curve means that a small increase in the amount of titrant will cause a large change in pH, allowing a variety of indicators to be used such as phenolphthalein or bromothymol blue. When dealing with a strong acid and a weak base, or vice versa, the titration curve becomes more irregular.

Weak acids and bases are molecules that do not fully dissociate when in solution, that is they are not salts.

An example of a weak acid is acetic acid ethanoic acidand an example of a weak base is ammonia. Because these molecules do not fully dissociate, the pH shifts less when near the equivalence point. The equivalence point will occur at a pH within the pH range of the stronger solution, i. For this reason, you must select the correct indicator for the right combination of solutions, as the range of colour changes needs to have the equivalence point in it.

For example, when using a strong acid and a weak base, an indicator that changes at a low pH is needed, such as methyl orange 3. As titrations curves using a weak acid and a weak base are highly irregular, indicators cannot be used accurately.

Instead, a pH meter is often used. The word titration comes from the French word tiltreoriginally meaning the "proportion of gold or silver in coins," later meaning the "concentration of a substance in a given sample.

It would not be until Mohr developed the modern burette in that the technique would become recognisable to us today, and has since become a popular method of performing analytical chemistry. Titrations have many applications in the modern world, although a lot of the original uses have been made redundant by more modern techniques:.Want to know how to calculate moles?

A mole is small, subterranean mammal belonging to the family Talpidae. Just kidding - we're sure you've never heard that joke before. A mole is how chemists define an amount of substance, useful when dealing with many different molecules reacting at once i.

The official International System of Units definition is that a mole is the amount of a chemical substance that contains exactly 6.

Prior to that, a mole was defined as the number of atoms in 12 grams of carbon an isotope of carbon.

Turns out that memorising that definition for my GCSE chemistry exam was pointless. So why do chemists use moles, and why do you need a mole calculator? Well, as we said above, it provides a useful metric when dealing with reactions. Maybe an example would explain it best. Lets say you want to neutralise 10 g of hydrochloric acid HCl in water with some sodium hydroxide NaOH. Now, you want the resulting solution to be perfectly neutral, so you don't want to add too much or to little NaOH, making it too basic or acidic respectively.

It is therefore useful to find out exactly how many molecules of HCl are in the solution. This is where moles come in handy. To know how to calculate moles, the equation is:. If you wanted to find the concentration of the hydrochloric acid, you could use our concentration calculator. Let's do a quick example to help explain how to convert from moles to grams, or grams to moles. We know we have 10 g of HCl, and it has a molecular weight of Lets plug these numbers into the above equation:.

We can work out the number of molecules by timesing the moles by Avogadro's constant above. Now we know the amount of molecules of HCl we have, and, since the reaction iswe need the exact same number of molecules of NaOH to neutralise it.

As we need to find the mass of NaOH to add, lets quickly rearrange the equation:. We hope this grams to moles calculator or moles to grams calculator will help you with your chemical calculations! You may also find our titration calculator of use to you. Embed Share via.

When you look around, even if you're sitting at home, you will notice many different objects. The majority of these materials are not pure.

They are, in fact, mixtures.

Mixtures consist of a collection of different compounds. Sometimes the number of elements may be quite high, or sometimes quite low, but as long as there is more than 1 element in an object, it is a mixture. Orange juice in your glass, a cup of tea, detergents in the bathroom or milk - all these substances are mixtures.

Mixtures are not limited to just liquids though, solids and gases can both be mixtures; even biological organisms are very complex mixtures of molecules, gases, and ions dissolved in water.

Homogeneous mixtures - components are uniformly distributed throughout the mixture, and there is only one phase of matter observed. They are also known as solutions and may occur in the solid, liquid or gaseous state.

It is not possible to simply separate the mixture components, but no chemical change has occurred to any of the components. Examples: sugar water, dishwashing detergent, steel, windscreen washer fluid, air. Heterogeneous mixtures - components of the mixture are not uniformly distributed and may have regions with different properties.

Different samples of the mixture are not identical. At least two phases are always present in the mixture, and it's usually possible to physically separate them. A few examples of such substances: blood, concrete, ice cubes in cola, pizzathe Pacific Ocean. Concentration is one of the most well known and most important parameters for anybody who works with any chemical substances or reactions. It measures how much of a substance is dissolved in a given volume of solution.

Chemists use many different units for describing concentration. However, the term molarityalso known as molar concentrationis the most common way of expressing the concentration.

You can offer coupons or discount codes to encourage buyers to share their feedback publicly. Or host periodic drawings and giveaways, and choose a winner from the pool of customers who submitted reviews in a certain timeframe. Rewarding customers for writing reviews is an acceptable practice. Buying reviews is something to avoid. Your offer should simply be for writing a review, not for writing a review with an angle or spin you requested.

You can further encourage customers to leave reviews if you make those reviews easy to write on mobile. Creating a place for customers to respond and leave a star rating, for example, is an easy task to perform on a smartphone. You can also get creative, and look to gather not just written reviews, but also data points from surveys. This will allow you to write web copy that you can use to set alongside customer reviews, while still making it easy to leave feedback on mobile.
