Calculate the volume occupied by 15 g of a gas at STP. Its relative molecular mass is 60.

Explanation

To calculate the volume occupied by 15 g of a gas at STP (Standard Temperature and Pressure), we can follow these steps:

### Step 1: Determine the number of moles of the gas.
To find the number of moles, we use the formula:
\[ \text{Number of moles} = \frac{\text{mass of the gas (g)}}{\text{molar mass (g/mol)}} \]
Given:
...
