Some Basic Concepts of Chemistry - Result Question 48

####48. Concentrated aqueous sulphuric acid is $98$ $H_{2} S O_{4}$ by mass and has a density of $1.80 g m L^{- 1}$ . Volume of acid required to make one litre of $0.1 M$ $H_{2} S O_{4}$ solution is

[2007]

(a) $16.65 m L$

(b) $22.20 m L$

(d) $11.10 m L$

Show Answer

Solution:

$= \frac{98 \times 1000}{98 \times 100} \times 1.80 = 18.0$

Suppose $V m L$ of this $H_{2} S O_{4}$ is used to prepare 1 lit. of $0.1 M H_{2} S O_{4}$

$∴ V \times 18.0 = 1000 \times 0.1$

or $V = \frac{1000 \times 0.1}{18.0} = 5.55 m L$ .
