Molarity to Parts Per Million Converter

Convert molarity (moles per liter) to parts per million (ppm) based on the molar mass of the solute.

Input Parameters

Calculation Results

Calculation Formula

ppm = Molarity (M) × Molar Mass (g/mol) × 1000

Where:
ppm = Parts per million
Molarity (M) = moles of solute per liter of solution
Molar Mass = mass of one mole of the solute (g/mol)

Learn how to use the Molarity to Parts Per Million Converter calculator and its working principles

How to Use the Calculator

  1. Enter the molarity (M) of the solution in mol/L. This is the number of moles of solute per liter of solution.
  2. Enter the molar mass (g/mol) of the solute. This is the mass of one mole of the solute.
  3. Click the "Calculate" button to compute the parts per million (ppm) of the solute in the solution.
  4. The result will be displayed in the "Parts Per Million (ppm)" field.

Working Principle

The calculator uses the formula: ppm = Molarity (M) × Molar Mass (g/mol) × 1000. This formula converts the molarity of a solution to parts per million, which is a measure of the concentration of a solute in a solution.

Example

If you have a solution with a molarity of 0.01 M and a molar mass of 58.44 g/mol (sodium chloride), the calculation would be:

ppm = 0.01 mol/L × 58.44 g/mol × 1000 = 584.4 ppm
