Answer:
mass percent = 3.98%
Explanation:
Solve for the mass of the solution.
mass solution = mass solute + mass solvent
mass solution = 4.35 g + 105 g
mass solution = 109.35 g
Solve for the mass percent.
mass percent = (mass solute / mass solution) × 100
mass percent = (4.35 g / 109.35 g) × 100
mass percent = 3.98%
