Explanation:

Haemoglobin is a protein found in red blood cells that is responsible for transporting oxygen from the lungs to the rest of the body.

Iron is an essential component of haemoglobin, as it is responsible for binding to oxygen.

The percentage of iron by mass in haemoglobin is approximately 0.33%.

The molecular mass of haemoglobin is 67200.

To find the number of iron atoms in each molecule of haemoglobin, we need to use the following formula:

Number of iron atoms = (percentage of iron by mass / atomic mass of iron) x molecular mass of haemoglobin

Substituting the values in the formula, we get:

Number of iron atoms = (0.33 / 55.85) x 67200

Number of iron atoms = 4

Therefore, the correct answer is option (b), which states that there are four iron atoms in each molecule of haemoglobin.

Iron content in haemoglobin = 0.33%by mass=0.33% of molecular mass=67200*0.33/100=221.76 it means this amount of mass of iron in 1 molecule of haemoglobin. number of iron atom present =221.76/atomic mass =221.76/56=3.96~4
