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 \( CO_2 \) gas, we can follow these steps:

### Step 1: Identify the given mass
The mass of \( CO_2 \) given is 22 grams.

### Step 2: Calculate the molar mass of \( CO_2 \)
The molar mass of \( CO_2 \) can be calculated using the atomic masses of carbon and oxygen:
- The atomic mass of carbon (C) is approximately 12 g/mol.
