Calculation of Iron Atoms in Haemoglobin Molecule
1. Given Data:
- Percentage of iron in haemoglobin = 0.334%
- Molecular weight of haemoglobin = 67200
- Atomic weight of iron (Fe) = 56
2. Calculation:
- Calculate the weight of iron in one molecule of haemoglobin:
Weight of iron = 0.334% of 67200
= (0.00334) * 67200
= 224.448
- Calculate the number of iron atoms in one molecule of haemoglobin:
Number of iron atoms = Weight of iron / Atomic weight of iron
= 224.448 / 56
= 4
3. Conclusion:
- Therefore, there are 4 iron atoms present in one molecule of haemoglobin. Hence, the correct answer is option 'C'.
