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 x 56
` therefore 0.335` g Fe is present in 100 g haemoglobin
` therefore 4 xx 56 = (100 xx 4 xx 56)/(0.335) = 66675`
