Explanation / Answer

C)
mass of solute = mass of solution - mass of solvent
= 237.1 g - 153.3 g
= 83.8 g

mass % = mass of solute * 100 / mass of solution
= 83.8 * 100 / 237.1
= 35.3 %

Answer: 83.8, 35.3

D)
mass % = mass of solute * 100 / mass of solution
mass % = mass of solute * 100 / (mass of solute + mass of solvent)
18.3 = mass of solute * 100 / (mass of solute + 305.2)
18.3 = m * 100 / (m + 305.2)
18.3 m + 5585.3 = 100 m
81.7 m = 5585.3
m = 68.4 g

mass of solution = mass of solute + mass of solvent
= 68.4 g + 305.2 g
= 374 g

Answer: 68.4, 374
