Chemistry - Liquid Solution Question with Solution | TestHub

Mass of solute (salt) = $50$ g

Mass of solvent (water) = $500$ g

Mass of solution = Mass of solute + Mass of solvent = $50+500=550$ g

Concentration of the solution = $\frac{\text{Mass of solute}}{\text{Mass of solution}}\times 100$

Concentration = $\frac{50}{550}\times 100=\frac{100}{11}\approx 9.09\%$

The closest value among the given options is $9\%$.

Answer: $9\%$
