Calculate :
The volume occupied by 80 g of ammonia at STP.

Explanation

To calculate the volume occupied by 80 g of ammonia (NH₃) at Standard Temperature and Pressure (STP), we will follow these steps:

### Step 1: Calculate the number of moles of ammonia
To find the number of moles, we use the formula:

\[ \text{Number of moles} = \frac{\text{Mass (g)}}{\text{Molar mass (g/mol)}} \]
