A 200.0 mL aqueous solution contains 58.8 mL of H₂SO₄. The concentration of the aqueous solution is _____ ppb. (Density of solution = 0.998 g/mL; density of H₂SO₄ = 1.84 g/mL) A) 0.542 × 10⁶ B) 0.530 × 10⁷ C) 5.42 × 10⁸ D) 58.8 × 10⁶ E) 5.42 × 10⁹

Question

Quizplus · Accepted Answer

To find the concentration in ppb, calculate the mass of H2SO4 and the total mass of the solution. Mass of H2SO4 = 58.8 mL × 1.84 g/mL = 108.192 g. Total mass of solution = 200 mL × 0.998 g/mL = 199.6 g. Concentration in ppb = (mass of solute/mass of solution) × 10^9 = (108.192/199.6) × 10^9 = 5.42 × 10^8 ppb.
