A gas cylinder contains `24 xx 10^(24)` molecules of nitrogen gas. If Avogadro's number is `6xx10^(23)` and the relative atomic mass of nitrogen is 14, calculate:
Mass of nitrogen gas in the cylinder.

Explanation

To calculate the mass of nitrogen gas in the cylinder, we can follow these steps:

### Step 1: Determine the molecular mass of nitrogen gas (N₂)
The relative atomic mass of nitrogen (N) is given as 14. Since nitrogen gas (N₂) consists of two nitrogen atoms, the molecular mass of nitrogen gas can be calculated as:
\[ \text{Molecular mass of N}_2 = 2 \times \text{Relative atomic mass of N} = 2 \times 14 = 28 \text{ g/mol} \]
