Solution Concentration Calculator
Calculate mass/volume percent, weight percent, and g/L concentration of solutions.
How It Works
Enter the mass of solute and the volume or mass of solution. The calculator computes three common concentration units: mass/volume percent (w/v%), mass percent (w/w%), and grams per liter (g/L).
Formula
w/v% = (g solute / mL solution) × 100 | w/w% = (g solute / g solution) × 100
Examples
5 g NaCl in 100 mL = 5% w/v | 10 g glucose in 200 g solution = 5% w/w
Frequently Asked Questions
What is w/v percent?
Weight/volume percent (w/v%) is grams of solute per 100 mL of solution. A 5% NaCl solution has 5 g NaCl in 100 mL.
What is w/w percent?
Weight/weight percent (w/w%) is grams of solute per 100 g of solution. Used when density makes volume measurement impractical.
How do I calculate g/L concentration?
Divide the mass of solute (g) by the volume of solution (L). This is the same as w/v% × 10.
