What is the percentage concentration by mass of a solution that contains 0 point 0 9 8 kilograms of cap h sub 2 SO sub 4 in 500 point 0 g of cap h sub 2 cap o ? Use mass percent is equal to mass of solute over mass of solution times 100

Convert the sulfuric acid mass to grams: 0.098 kg = 98 g. The total solution mass is 98 g + 500.0 g = 598.0 g, so the mass percent is (98 ÷ 598) × 100 ≈ 16.4%. This rounds to 16 percent, choice C.
