Formula
%(w/v) = (mass in g / volume in mL) x 100 Symbol legend
| Symbol | Meaning | Unit | Copy |
|---|---|---|---|
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 m = 5 g
- 2 V = 100 mL
- 3 %(w/v) = (5 / 100) x 100 = 5%
The concentration is 5% (w/v).
How
- Enter mass of solute in grams.
- Enter final solution volume in milliliters.
- 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.
