## Molarity to PPM Formula

The formula for converting molarity to ppm

**PPM = M × MM × 1000**

- PPM = Parts Per Millions
- MM = Molar Mass (g/mol)
- M = Molarity (mol/L)

## How to convert Molarity to PPM?

To convert molarity (M) to parts per million (ppm), follow these steps:

- Determine the molar mass (MM) – The molar mass is the sum of the atomic masses of all the atoms in the molecule
- Multiply the molarity by the molar mass then you get mg/L
- Finally, Multiply the mg/L by 1000

## Solved Example

**Example – **A solution of 0.1 M NaCl. The molar mass of NaCl is 58.44 g/mol. To convert the molarity of NaCl to ppm

**Solved**

Given values – Molarity = 0.1 M, Molar Mass = 58.44 g/mol

Put all values into the formula

PPM = 0.1 × 58.44 × 1000 = 5844 ppm

so, the concentration of NaCl in the solution is 5844 ppm.
