Hameoglobin contains 0.25% iron by weight. The molecular weight of hameglobin is 896000. Calculate the number of iron atom per molecules of haemoglobin.

Explanation

To solve the problem of calculating the number of iron atoms per molecule of hemoglobin, we can follow these steps:

### Step 1: Understand the given data
- The percentage of iron in hemoglobin = 0.25% by weight
- Molecular weight of hemoglobin = 896,000 g/mol

### Step 2: Calculate the weight of iron in one mole of hemoglobin
To find the weight of iron in one mole of hemoglobin, we can use the percentage by weight:
