MCQ

When $17\,g$ of $H_2A$ (dibasic acid) completely neutralised with $100\,mL,\,\,1\,M\,BOH$ (monoacidic base) then molecular weight of acid is

A
$170$
✓
$340$
C
$85$
D
None of these

✓

Answer

Correct option: B.

$340$

b
Gram equivalents of acid $=$ Gram equivalent of base

${\frac{17}{\mathrm{E}_{\mathrm{w}}}=1 \times 1}$

${\mathrm{E}_{\mathrm{w}}=170}$

${\mathrm{M}_{\mathrm{w}}=2 \times 170=340}$
