Solution concentration by blending
Mix two solutions of the same solute using mass percentages.
A clear answer. Here’s how.
Solute mass = solution mass × mass fraction for each input. Adds masses and divides combined solute by total solution mass to obtain the blend’s mass percentage. Assumes the same solute definition, no reaction or loss and additive mass; it does not assume additive liquid volumes or infer density.

Worked example
A fixed demonstration, separate from the values you enter above.
- First solution mass (g)
- 200
- First solute concentration (% by mass)
- 10
- Second solution mass (g)
- 300
- Second solute concentration (% by mass)
- 2
Example result
- Blended mass concentration
- 5.2 %
- Combined solution mass
- 500 g
- Combined solute mass
- 26 g
- Combined remaining mass
- 474 g
