Calculate the volume occupied by 2.8 g of `N_2` at STP.

Explanation

To calculate the volume occupied by 2.8 g of \( N_2 \) at STP (Standard Temperature and Pressure), follow these steps:

### Step 1: Determine the molecular mass of \( N_2 \)
The molecular mass of nitrogen (\( N \)) is approximately 14 g/mol. Since nitrogen exists as a diatomic molecule (\( N_2 \)), the molecular mass of \( N_2 \) is:
\[ \text{Molecular mass of } N_2 = 2 \times 14 = 28 \text{ g/mol} \]
