Molarity from % CompositionHardQuestion 600047

Question

Concentrated H₂SO₄ is 98% by weight and has density 1.84 g/mL. Its molarity (M = 98) is:
  1. A
    9.2 M
  2. B
    18.4 M
    Correct
  3. C
    36.8 M
  4. D
    4.6 M

Correct answer

18.4 M

Explanation

M = (% × density × 10) / Mmolar = (98 × 1.84 × 10) / 98 = 18.4 M.
