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:

A

4.5 g

B

6.3 g

C

0.63 g

D

0.45 g

Text Solution

Verified by Experts

The correct Answer is:
C
`H_(2)C_(2)O_(4).2H_(2)O=2+24+64+36=126` and Equivalent wt. `=[(126)/(2)]`
`0.2=(Wxx1000)/(((126)/(2))xx50) " " :. W=0.63 g`
