Calculate the number of moles of 22g of `CO_2` gas enclosed in a cylinder.

Explanation

To calculate the number of moles of 22 grams of carbon dioxide (CO₂) gas enclosed in a cylinder, we can follow these steps:

### Step 1: Understand the formula for calculating moles
The number of moles (n) can be calculated using the formula:
\[ n = \frac{\text{mass (g)}}{\text{molar mass (g/mol)}} \]

### Step 2: Determine the molar mass of CO₂
To find the molar mass of carbon dioxide (CO₂):
