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 will follow these steps:

### Step 1: Determine the amount of iron in 100 grams of hemoglobin.
Given that hemoglobin contains 0.25% iron by weight, we can find the amount of iron in 100 grams of hemoglobin.

\[ \text{Amount of iron} = \frac{0.25}{100} \times 100 \, \text{grams} = 0.25 \, \text{grams} \]
