Q. If $1 g m$ of propionic anhydride is introduced quantitatively into water, calculate the volume of $0.5 N$ alkali required for neutralisation of the solution?

$30.8 m l$

$44.4 m l$

$61.6 m l$

$50 m l$

$1 m o l (130 g m) = 2 m o l$
$1 g m = \frac{2}{130}$ mol or eq.
Number of equivalent of acid $=$ Number of equivalent of base
$\frac{2}{130} \times 1000 m Eq = 0.5 \times V$
$∴ V = 44.4 m l$
