Formula
%(w/v) = (mass in g / volume in mL) x 100

m Solute mass g
V Solution volume mL
\%(w/v) Percent mass/volume concentration %
  • Enter solute mass in grams.
  • Enter total solution volume in mL.
  • Apply ratio times 100 to obtain percent concentration.
Example

Worked example: 5 g in 100 mL

  1. 1 m = 5 g
  2. 2 V = 100 mL
  3. 3 %(w/v) = (5 / 100) x 100 = 5%

The concentration is 5% (w/v).

How
  1. Enter mass of solute in grams.
  2. Enter final solution volume in milliliters.
  3. Read percent concentration output.
Avoid
  • Using solvent volume instead of final solution volume.
  • Mixing w/w and w/v conventions.
  • Confusing percent units with molarity units.

Ref only. Verify values. Follow lab safety.

FAQ
Is this w/v percent or w/w percent?

This calculator is for w/v percent: grams per 100 mL solution.

Can I use liters for volume?

Yes, but convert to mL first or use a converter before input.

Does this give molarity?

No, molarity requires molar mass and liter volume.
