Question

Which of the following expressions can be used for calculating the concentration of a solution formed by dissolving sugar in water?
(More than one option is correct)

• A. $\frac{\text{Mass of solvent}\times 100}{\text{Volume of solution}}$
• B. $\frac{\text{Volume of solvent}\times 100}{\text{Mass of solution}}$
• C. $\frac{\text{Mass of solute}\times 100}{\text{Mass of solute + Mass of solvent}}$
• D. $\frac{\text{Volume of solute}\times 100}{\text{Volume of solution}}$

Answer 1

Answer: (C), (D)

$\frac{\text{Volume of solute}\times 100}{\text{Volume of solution}}$

The concentration of a solution is the amount of solute present in a given amount (mass or volume) of the solution.

• $\text{m/m \%}=\frac{\text{Mass of solute}}{\text{Mass of solution}}\times 100$

$=\frac{\text{Mass of solute}}{\text{Mass of solute + Mass of solvent}}\times 100$

• $\text{v/v \%}=\frac{\text{Volume of solute}}{\text{Volume of solution}}\times 100$

$=\frac{\text{Volume of solute}}{\text{Volume of solute + Volume of solvent}}\times 100$
