Question

prepare 100 ml of M/20 oxalic acid solution. m = 0.63g

Answer 1

Answer:

0.1575g

Explanation:

• To prepare 100ml of M/20 oxalic acid
• Given M= 0.63g
• Hydrated oxalic acid=C2H2O4.2H20
• 0.63g of oxalic acid per litre of the solution should be dissolved to prepare m/20 oxalic acid solution is
• 0.63/4=0.1575g

Answer 2

The prepare $100ml$ of $\frac{m}{20}$ oxalic acid in 0.1575g.

Explanation:

To prepare $100ml$ of $\frac{m}{20}$ oxalic acid.

$m=0.63g$

$0.63g$ of oxalic acid per litre of the solution should be dissolved to prepare

$\frac{m}{20}$ oxalic acid solution is,

$=\frac{0.63}{4}$

$=0.1575g$.
