Question

1. Concentrated aqueous sulphuric acid is
98% H2SO4 by mass and has a density of
1.80 gmL". Volume of acid required to make
one litre of 0.1 M H2SO, solution is
[CBSE AIPMT 2007]
(a) 11.10 mL
(b) 16.65 ml
(C) 22.20 ml
Vely 5.55 mL​

Answer 1

Answer:

Answer: (3)

Molarity of H2SO4 solution = number of moles of the solute/Volume of solution given in terms of litres

\(Molarity of H2SO4 solution = \frac{98 times 10 00}{98 times 100}times 1.802\)

Molarity of H2SO4 solution (M1) = 18.02

Let us consider V1 volume of H2SO4 is used to prepare 1 litre of 0.1M of H2SO4.

Using formula

M1V1 = M2V2

V1 = M2V2/M1

V1 = 1000 × 0.1 / 18.02

V1 = 5.55ml
