PPM to Molarity Calculator
This PPM to Molarity calculator makes the conversion of ppm to molarity for any molecule or element dissolved in water.
PPM stands for parts per million is a unit that is used in several branches in different ways. On the other hand, molarity tells us that in one liter of water how many moles of molecules present?

Formula of PPM to Molarity Calculator
To convert ppm to molarity we can divide the ppm by 1000. The complete formula is given below.
Molarity = ((ppm * 0.001) / molar mass)
Note:
To calculate the molar mass of gas, you can use our Molar Mass Of Gas Calculator.
Example
Calculate the molarity (mol/L) if there is 70 ppm of Ca2+ ions. And, 33 g/mol is the atomic weight of calcium ions.
Given data
ppm value = 70 ppm
molar mass = 33 g/mol
To Find
molarity = ?
Solution
To convert PPM to molarity, let us use the formula listed below:
Molarity = ((ppm * 0.001) / molar mass)
Putting values in the formula:
molarity = (70 * 0.001) / 33
molarity = 0.0021 mol/l
