Concentrated aqueous sulphuric acid is 98% H2SO4 by mass and has a density of 1.80 g mL−-−1. Volume of acid required to make one litre of 0.1 M H2SO4 solution is
  1. A
    16.65 mL
  2. B
    22.20 mL
  3. C
    5.55 mL
  4. D
    11.10 mL

Correct answer: C

Normality = 98×1.8×1049{{98 \times 1.8 \times 10} \over {49}}4998×1.8×10​ = 36 N

N2 = 0.1 ×\times× 2 = 0.2 N

N2V2 = N1V1

⇒\Rightarrow⇒ 36 ×\times× V = 0.2 ×\times× 1000

⇒\Rightarrow⇒ V = 0.2×100036{{0.2 \times 1000} \over {36}}360.2×1000​ = 5.55 mL
