Molarity Calculator - An Introduction
In the realm of chemistry, calculating molarity and its concentrations is an important task. Therefore, having a reliable molarity formula calculator can ease complex concentration calculations. This online calculator provides instant results, eliminating the need for manual calculations.
Our molarity volume calculator helps you determine the molarity whether you are a student or a professional. It gives you accurate answers and solves your problems of finding the molarity.
What is meant by molarity?
The number of moles of solute dissolved in a solution per dm3 is molarity. Molarity is also known as molar concentration as it involves finding the number of moles in a solution. For solutions, the volume that is taken is in dm3. Molarity is donated by capital M.

Why molarity is important?
Molarity expresses the concentration of a solution. If the molarity of a certain solution is known to you then you will not just be able to get whether the solution is concentrated or diluted but also know the actual concentration of the solution.
The formula of molarity used by molarity calculator:
In molarity, the moles of solute and the liters of solution are used to find the actual concentration or know the solution’s concentration. The solute and solution values are found to find molarity. It is the ratio between them and our molarity solution calculator uses the same formula which is,
Molarity (M) = (Mass of solute / Molar mass of solute) * (1 / volume of solution per dm3)
If the mass and molar mass of the solute is known then this formula can be used but if the number of solute is present then the other formula is,
Molarity = No. of moles of solute / Volume of solution per dm3
How to find molar concentration?
To calculate the molarity of a solution you should know about the known things. First, the moles of solute and the volume of the solution or you may know the mass of solute, molar mass, and the volume of solution per dm3. For finding the molar mass, our molar mass determiner is here to give you a helping hand.
It is important to calculate molarity by using a molarity calculator for solutions and it can also be found out manually. We are going to give you some examples so that you can know how to find molarity manually.
Example 1:
A solution contains 20.7g of K2CO3 which is dissolved in 500cm3 of the given solution. Find the molarity of the solution.
Solution:
The mass of K2CO3 = 20.7g
The molar mass of K2CO3 = 138g/mol
The volume of the given solution = 500 cm3
To convert cm3 to dm3 we will divide it by 1000. So we will get,
500/1000 = 0.5 dm3
By putting the formula of molarity,
M = (20.7/138) * (1/0.5)
= 0.3 mol dm^-3
The molarity of the solution is 0.3 mol dm^-3.

Example 2:
By bubbling 1.56 g of hydrochloric acid in water, a solution is prepared. The volume of the solution is 28.6 mL. Find the molarity of this solution.
Solution:
First, we will find the molecular weight of HCl and H2O
The molecular weight of hydrochloric acid (HCl) = 35.5 ×1 + 1×1 = 36.5 mol/g
The molecular weight of water (H2O) = 1 ×2 + 16 ×1 = 18 moles/gram
The given mass of hydrochloric acid in the solution = 1.56 g
The number of moles of hydrochloric acid (HCl) = 1.56/36.5 = 4.27 * 10^-2 mol
The given volume of solution = 28.6/1000 = 2.86 * 10^-2 Liter
Calculating the molarity of the solution = 4.27 * 10^-2 / 2.86 * 10^-2
= 1.49 M
So the molarity of the solution is 1.49 M.
If its hard to determine the molecular weight of HCl or H2O or any other complex molecule or compound then feel free to use our Molecular formulas calculator.
Difference between molarity and Molality
We found molarity and molality for the solutions but there are some differences as well that are given below,
|
Molarity |
Molality |
|
Molarity is the moles of solute per liter of the solution. |
Molality is the moles of solute per Kilogram of the solvent. |
|
It is denoted by M. |
It is denoted by m. |
|
The formula of molarity is, M = no. of moles of solute/liters of solution. |
The formula of molality is, m = No. of moles of solute / Kg of solvent. |
|
It is easy to work with molarity but temperature differences can affect the volume. |
Temperature differences don’t affect the volume. |
Suggested: You can use our molal calculator if you are curious about finding the molality of solutions.
