Calculate the total number of electrons present in `3.2 g` of oxygen gas.

Explanation

To calculate the total number of electrons present in 3.2 g of oxygen gas (O₂), we can follow these steps:

### Step 1: Determine the molar mass of oxygen gas (O₂).
The molar mass of a single oxygen atom (O) is approximately 16 g/mol. Since oxygen gas is diatomic (O₂), the molar mass of O₂ is:
\[ \text{Molar mass of O}_2 = 2 \times 16 \, \text{g/mol} = 32 \, \text{g/mol} \]
