haemoglobin contains 0.334% of iron by weight . the molecular weight of haemoglobin ia approximately 67200. what is the number of iron atoms present in one molecule of haemoglobin? ( given that atomic wt of iron is 56)
sir could you please answer as soon as possible?

Expert Answer
Percentage of Fe = 0.33% molecular weight of haemoglobin
Weight of Fe present = (0.33/100) × 67200 = 221.8
one Fe weighs 55.8 g
Therefore, 221.8/55.8 = 4
Hence, 4 atoms of iron are present in one molecule of haemoglobin.
