Question

What is the molarity of H2SO4 solution that has a density of 1.84 g/cc and contains 98% by mass of H2SO4? (Given atomic mass of S = 32)

• A. 4.18 M
• B. 8.14 M
• C. 18.4 M
• D. 18 M

Answer 1

Answer: (C)

18.4 M

Answer 2

(3)

Molarity$= \frac{98 \times 10 \times 1.84}{Gmm} = 18.4M \{\therefore M = \frac{(\% w/w) \times (d) \times 10}{Mol.massofsolute}\}$

(d in gm/ml.)
