The mass of oxalic acid crystals (H(2)C(...

The mass of oxalic acid crystals `(H_(2)C_(2)O_(4).2H_(2)O)` required to prepare 50 mL of a 0.2 N solution is:

126 g

12.6g

63g

6.3 g

Text Solution

Verified by Experts

The correct Answer is:

Molecular wt. of `H_(2)C_(2)O_(4). 2 H_(2)O = 126`
`H_(2)C_(2)O_(4).2H_(2)O` is dibasic acid gm. Equivalent wt.is half of molecular wt.
