Calculate the number of nitrogen molecules present in `2.8 g` of nitrogen gas.

Explanation

To calculate the number of nitrogen molecules present in 2.8 g of nitrogen gas (N₂), we can follow these steps:

### Step 1: Calculate the number of moles of nitrogen gas (N₂)
The formula to calculate the number of moles is given by:

\[ \text{Number of moles} = \frac{\text{Weight of the substance (g)}}{\text{Molecular weight of the substance (g/mol)}} \]
