Question

Calculate the mass of a solute in a 10% salt solution if the mass is 350 grams.

Answer 1

Answer: The mass of a solute is 35 grams

Explanation:

To calculate the mass percentage of solute, we use the equation:

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

Mass percent of solute = 10 %

Mass of solution = 350 g

Putting values in above equation, we get:

$10=\frac{\text{Mass of solute}}{350g}\times 100\\\\\text{Mass of solute}=\frac{10\times 350}{100}=35g$

Hence, the mass of a solute is 35 grams
