A 400 mg iron capsule contains 100 mg of ferrous fumarate, `(CHCOO)_(2)`Fe. The percentage of iron present in it is approximately

A

0.33

B

0.25

C

0.14

D

0.08

Text Solution

Verified by Experts

The correct Answer is:
D
Molecular weight of `(CHCOO)_(2) Fe=170`
Fe present in 100 mg of `(CHCOO)_(2)Fe`
`=56/170xx100mg =32.9 mg`
This is present in 400 mg of capsule
% of Fe in capsule `=32.9/400xx100=8.2`.
