Answer :
For a solute to be quantified, one must know its mass or moles. By multiplying the grams of solute per gram of solution by 100, one may get the mass percent of a solution.
Why does the equation C1V1 C2V2 work?
Because the overall amount remains constant, the starting concentration times the initial volume will equal the final concentration times the final volume. As a result, C1V1 = C2V2, which is an equation.
35 mL of ethanol and 65 mL of water combined to make a solution with a volume percent by volume of 35%. The mass or volume of solute required may also be determined if you know the concentration.
