How to Calculate Concentration - ThoughtCo

5/9/2018· How to Calculate Volume Percent Concentration of a Solution Volume percent is the volume of solute per volume of solution. This unit is used when mixing together volumes of two solutions to prepare a new solution. When you mix solutions, the volumes aren''t always additive, so volume percent is a good way to express concentration.

Percent Concentration - Chemistry | Socratic

Percent concentration by mass is defined as the mass of solute divided by the total mass of the solution and multiplied by 100%. So, c% = msolute msolution ⋅ 100%, where. msolution = msolvent + msolute. There are two ways to change a solution''s concentration by mass. Adding more solute - making the solution more concentrated;
