The haemoglobin from the red blood corpuscles of most mammals contains approximately `0.33%` of iron by weight. The molecular weight of haemoglobin is `67,200`.
The number of iron atoms in each molecule of haemoglobin is (atomic weight of iron `=56`):

A

`2`

B

`3`

C

`4`

D

`5`

Text Solution

Verified by Experts

The correct Answer is:
C
`100 g "sample"-=0.33 "iron"`
`67200 g-=221.8 g "iron"`
`:.` Number of iron atoms per molecule of haemoglobin `=(221.8)/(56)=4`
