Question

molecular weights of haemiglobin

a. 16500
b. 35000
c. 65000
d. 85000​

Answer 1

Answer:

The number of moles of Fe present in one mole of haemoglobin is 65000 g/mol haemoglobin×

100 g haemoglobin

0.35 g iron

×

55.8 g iron

1 mol iron

=4 mol

Thus, 1 mole of haemoglobin contains 4 moles of Fe.

Hence, 1 molecule of haemoglobin contains 4 molecules of Fe.
