Calculation of Iron atoms in Hemoglobin

Given Data:
- Percentage of iron in hemoglobin = 0.33%
- Molecular weight of hemoglobin = 67200

Step 1: Calculate the weight of iron in one molecule of hemoglobin
- 0.33% of 67200 = (0.33/100) * 67200 = 221.76 grams of iron in one molecule of hemoglobin

Step 2: Calculate the number of moles of iron in one molecule of hemoglobin
- Moles = Weight / Atomic weight
- Atomic weight of iron = 55.85 g/mol
- Moles of iron = 221.76 g / 55.85 g/mol = 3.97 moles

Step 3: Calculate the number of iron atoms in one molecule of hemoglobin
- 1 mole of any substance contains Avogadro's number of particles (6.022 x 10^23)
- Number of iron atoms = Moles of iron * Avogadro's number
- Number of iron atoms = 3.97 moles * 6.022 x 10^23 = 2.39 x 10^24 iron atoms
Therefore, there are approximately 2.39 x 10^24 iron atoms present in one molecule of hemoglobin.
