Molarity can simply be defined as a unit of concentration. It describes the relationship between the moles of a solution and the solution’s density. It is calculated by measuring the quantity number of moles in a solute for every liter of a solution. In molarity, there are two elements, that’s a solution and a solute. The solution is a combination of a mixture of a liquid and a solute. A solute is a solid compound that dissolves in a liquid in a certain condition. When calculating molarity of a solution, the most important thing to do is remember the unit of molarity; which is M per liter. Secondly, molarity can either be calculated manually or using tools like a molarity calculator or __molar concentration calculator__.

**How to calculate the molarity of a solution?**

Firstly, you can calculate molarity using moles and volume. In this case, molarity can be calculated by dividing the moles number in a solute and solution volume. Therefore, you will need the volume of that solution but when calculated in liters. Then you need to find the number of moles of the solute in the solution. This is if you have not been provided with this information beforehand. Dividing the mole number by the numbers of liters will give you the number of moles per liter. It is as simple as that!

You can also calculate molarity using mass and volume. It is impossible to calculate the molarity of a solution without the number of moles and volume. Therefore, you can use the mass of a solute to calculate its molarity.

If you do not know the number of moles but have the volume and mass of the solution, you can use this information to calculate the moles. You can start by calculating the molar mass of the solute. All you have to add together the molar masses of each element found in the solution. NB: the molar mass can be found on the periodic table.

Next, convert the grams into moles by multiplying the number of grams of the solute with (1 mole over the molar mass). With the molar mass and the volume, you can proceed to calculate the molarity of the solution.

You can also calculate the molarity using the number of moles and milliliters. This is one of the most straightforward questions to answer. That is if you have mastered the formula for calculating molarity. The first step would be to convert the volume of the solution from milliliters to liters. Then, calculate the molarity by dividing the number of moles by the liters.

**Conclusion**

Note, the method you use when calculating molarity greatly depends on the question and the information provided. Molarity can also be referred to as molar concentration or the amount of substance concentration. It’s referred to as the density of a mixture divided by the molar mass of the same mixture. Molarity is a common term used in Chemistry. In schools, students are required to calculate molarity as part of a chemistry examination. However, the task can be made easier using molarity calculator tools on the internet.
