Calculate the mass of 2.8 litres of `CO_(2)` at S.T.P.

Explanation

To calculate the mass of 2.8 liters of CO₂ at Standard Temperature and Pressure (S.T.P.), we can follow these steps:

### Step 1: Determine the Molar Mass of CO₂
The molar mass of CO₂ can be calculated by adding the atomic masses of its constituent elements:
- Carbon (C) has an atomic mass of 12 g/mol.
- Oxygen (O) has an atomic mass of 16 g/mol, and there are 2 oxygen atoms in CO₂.

So, the molar mass of CO₂ is:
