    Answer:

    37.5 g NaCl

    Explanation:

    Step 1: Given data

    • Concentration of NaCl: 15.0% m/m
    • Mass of the solution: 250.0 g

    Step 2: Calculate how many grams of NaCl are in 250.0 g of solution

    The concentration of NaCl is 15.0% by mass, that is, there are 15.0 g of NaCl every 100 g of solution.

    250.0 g Solution × 15.0 g NaCl/100 g Solution = 37.5 g NaCl
