# Moles to Molarity Calculator

 Molarity:

Free online moles to molarity calculator – calculate molarity from moles just mole and volume then click the calculate button.

## Moles to molarity formula

To calculate molarity from moles, you can use the formula

M = n / v = moles (mol)/volume (L)

• n = Moles of solute (mol)
• M = Molarity (M or mol/L)
• V = Volume of solution (L)

## How to convert moles to molarity?

To convert moles to molarity, simply moles of solute divide by the volume of solution then you get molarity (mol/L).

Here step by step

1. First, Determine the moles of solute (mole = mass/molar mass)
2. Next, Determine the volume of the soln (liter)
3. Finally, Put values in the above formula of moles to molarity

## Solved Example

Example – 0.5 moles of NaCl dissolved in 2 liters of water. The molarity would be.

Given Values

• Moles of NaCl = 0.5 mol
• Volume of water = 2 liters

put the value into the formula

Molarity (M) = moles/volume = 0.5 / 2 = 0.25 M

The molarity of the solution is 0.25 M
