Q. The solution of sulphuric acid contains $80%$ by weight $H_{2} S O_{4}$ . Specific gravity of this solution is $1.71$ . Its normality is about

$18.0$

$27.9$

$1.0$

$10.0$

$N = \frac{10 \times sp. gr. og the solution \times wt. % of solute \times Mol. wt}{Molecular wt. of solute \times Eq. wt.}$
$N = \frac{10 \times 1.71 \times 80 \times 98}{98 \times 49}$
$= 27.9$
