Enter the ppm and the molar mass of a substance into the calculator to determine the molarity. This calculator can also determine the PPM or molar mass given the molarity and the other variable.

## PPM to Molarity Formula

The following equation is used to convert PPM to molarity.

M = PPM/ mm / 1000

- Where M is the molarity
- mm is the molar mass (g/mol)
- PPM is the parts

To calculate molarity from ppm, divide the PPM by the molar mas (g/mol), then divide the result by 1000.

## PPM to Molarity Conversion

The conversion of PPM to molarity involves using the molar mass along with the equation above to calculate molarity.

## PPM to Molarity Example

How to convert PPM to molarity?

**First, determine the PPM.**Calculate the total parts per million of the solution or substance.

**Next, determine the molar mass.**Measure or calculate the molar mass in g/mol.

**Finally, calculate the molarity.**Calculate the molarity with the equation above.
