Solution Concentration Calculator
Mass/Volume Concentration
Mass Percent (w/w%)
Volume Percent (v/v%)
Formula
g/L = (mass_solute / volume_solution) × 1000 | w/w% = (mass_solute / mass_solution) × 100 | v/v% = (vol_solute / vol_solution) × 100
Frequently Asked Questions
What are the different ways to express concentration?
Concentration can be expressed as molarity (mol/L), mass percent (w/w%), volume percent (v/v%), mass/volume (g/L or mg/mL), ppm, ppb, molality, and normality. The choice depends on the application.
What is the difference between mass percent and volume percent?
Mass percent (w/w%) is the mass of solute divided by total solution mass × 100. Volume percent (v/v%) is the volume of solute divided by total solution volume × 100. Mass percent is more precise since volumes can change with temperature.
