Calculate the mass of calcium that will contain the same number of atoms as are present in 3.2 gm of sulphur. [Atomic masses : S = 32, Ca = 40]

Explanation

To solve the problem of calculating the mass of calcium that contains the same number of atoms as are present in 3.2 grams of sulfur, we can follow these steps:

### Step 1: Calculate the number of moles of sulfur in 3.2 grams.
The molar mass of sulfur (S) is given as 32 g/mol.

\[ \text{Number of moles of sulfur} = \frac{\text{mass of sulfur}}{\text{molar mass of sulfur}} = \frac{3.2 \, \text{g}}{32 \, \text{g/mol}} = 0.1 \, \text{mol} \]
