If dry air is considered to have average molecular mass 28.84. What is the composition of dry Air?

Explanation

To determine the composition of dry air given its average molecular mass of 28.84 g/mol, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Components of Dry Air**:
Dry air is primarily composed of nitrogen (N₂) and oxygen (O₂). The molecular masses of these gases are:
- Nitrogen (N₂): 28 g/mol
- Oxygen (O₂): 32 g/mol
