Question

If $50\text{g}$ of sugar is present in $450\text{g}$ of water, what is the mass percentage of sugar in the solution.

• A. $9\%$
• B. $10\%$
• C. $50\%$
• D. $55\%$

Answer 1

The correct option is B $10\%$

Mass of the solute i.e. sugar $=50\text{g}$
Mass of the solvent i.e. water $=450\text{g}$
Mass of the solution $=50+450=500\text{g}$

$\therefore \frac{\text{mass}}{\text{mass}}\%=\frac{50}{500}\times 100=10\%$
