(a) Calculate the volume occupied at STP by
(i)16.0 g of oxygen (ii) 1.5 moles of oxygen and (iii) `6.022xx10^(23)` molecules of carbon dioxide

Explanation

To solve the problem, we will calculate the volume occupied at STP (Standard Temperature and Pressure) by the given amounts of oxygen and carbon dioxide.

### Step-by-Step Solution:

#### (i) Calculate the volume occupied by 16.0 g of oxygen (O₂):

1. **Determine the molar mass of O₂**:
- The atomic mass of oxygen (O) is 16 g/mol.
