Answer and explanation
Correct answer: 144 g
A 4% by-mass solution contains 4 g solute in every 100 g solution. If solute mass is 6 g, total solution mass = 6 × 100/4 = 150 g. Solvent mass is total solution mass minus solute mass: 150 − 6 = 144 g. The 150 g value is the total solution, not the solvent.
