Haemoglobin is a compound of iron. It contains 0.335% iron. If one molecule of haemoglobin contains four iron atoms its molecular weight will be (Fe= 55.84)

A

5584

B

66675

C

666.75

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
Atomic weight of Fe = 56
Weight of 4 Fe atoms `= 4 xx 56`
`because` 0.335 g Fe is present in 100 g haemoglobin
`therefore4xx56=(100xx4xx56)/(0.335)=66675`
