How It Works
How to Calculate Mass Percent
Formula
Mass % = (mass of solute / mass of solution) × 100
Mass percent tells you the grams of solute per 100 grams of solution.
Worked Example
10 g of salt dissolved in 90 g of water (100 g solution).
mass_solute = 10mass_solution = 100
- 01Mass % = (10 / 100) × 100
- 02Mass % = 10%
