Interpretation:Number of ${\text{Fe}}^{2+}$ ions in one molecule of $\text{Hb}$ is to be calculated.

Concept introduction: The formula to convert moles to mass in grams is as follows:

  $\text{Mass}=\left(\text{Number of moles}\right)\left(\text{molar mass}\right)$

The formula to convert the number of atoms to moles is as follows:

  $\text{Number of moles}=\frac{\text{Given number of molecules}}{6.022\times {10}^{23}}$
