If `1 gm` of propionic anhydride is introduced quantitatively into water, calculate the volume of `0.5 N` alkali required for neutralisation of the solution ?

Options

A. `10.8 ml`
B. `44.4 ml`
C. `61.6 ml`
D. `50 ml`

Answer

B

Explanation

`1 mol (130 gm) = 2 mol`
`1 gm = (2)/(130) mol` or `eq.`
Number of equivalent of acid = Number of equivalent of base.
`(2)/(130) xx 1000 mEq = 0.5 xx V`
`:. V = 44.4 ml`.
