Question

To prepare 2 $d{m}^3$ of decinormal solution of oxalic acid, the mass of oxalic acid required is

• A. 6.3 g
• B. 0.63 g
• C. 12.6 g
• D. 1.26 g

Answer 1

Answer: (C)

Normality $=\frac{1}{10}N$
Volume $=2d{m}^3$
Now, $N=\frac{w}{\text{ Eq.wt }\times \text{ Volume in }L\text{ or }d{m}^3}$
$\Rightarrow w=N\times Eq\cdot wt\times$ Volume
$=\frac{1}{10}\times 63\times 2=12.6g$
