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 100mg of `(CHCOO)_(2)` Fe ` = (56)/(170) xx 100 mg` = 32.9 mg
This is present in 400mg of capsule
% of Fe in capsule` = (32.9)/(400) xx 100 = 8.2`
