50ml of 1M oxalic acid is shaken with `0.5g` of wood charcoal. The final concentration of the solution after adsorption is 0.5M. Amount of oxalic acid absorbed per gm of charcoal is

A

3.45 g

B

3.15 g

C

6.30 g

D

None

Text Solution

Verified by Experts

The correct Answer is:
C
`W = (126xx1xx50)/(1000) implies 6.3`
(Molecular weight of oxalic acid `implies` 126)
`0.25 g to (6.3)/(2) implies1 g to (6.3)/(2xx0.5) xx1 implies 6.3 g`.
