Question

A solution is prepared with 10 grams of solute in 100 grams of water. The mass percentage of the solution is ___%.

Answer 1

Mass percentage is used to measure the concentration of a solution.

Mass by mass percentage of a solution $=\frac{\text{Mass of the solute}}{\text{Mass of the solution}}\times 100$

As we know a solution is a mixture of solute and solvent, the total amount of solution $=110g$

Mass percentage of a solution containing 10 gm of solute in 100 gm of water is $\frac{10}{110}\times 100=9.09\%$.
