To solve the problem of determining how many iron atoms are present in a hemoglobin molecule, we can follow these steps: ### Step 1: Determine the weight of iron in hemoglobin Given that the weight percentage of iron in hemoglobin is 0.33%, we can calculate the weight of iron in a sample of hemoglobin weighing 68,000 grams (the approximate molecular weight of hemoglobin). \[ \text{Weight of Iron} = \left( \frac{0.33}{100} \right) \times 68000 = 0.0033 \times 68000 = 226.8 \text{ grams} \] ...
