Solution

## Step 1: Given data:As, 1 mole of a substance = $6.022×{10}^{23}$(Avogadro number)No, of Oxygen atoms present in Vitamin C: $2.58×{10}^{24}$Step 2: To find the number of moles of Oxygen atom in the sample:$\mathrm{The}\mathrm{number}\mathrm{of}\mathrm{moles}=\frac{\mathrm{Given}\mathrm{number}\mathrm{of}\mathrm{particles}}{\mathrm{Avogadro}\mathrm{Number}}$$\mathrm{The}\mathrm{number}\mathrm{of}\mathrm{moles}\mathrm{of}\mathrm{Oxygen}\mathrm{atom}=\frac{2.58×{10}^{24}}{6.022×{10}^{23}}$$\mathrm{n}=4.28\mathrm{mol}$Therefore, $4.28\mathrm{moles}$ of the Oxygen atom are present in the sample.
