A gas is composed of 30.4% N and 69.6% O. Its density is 11.1 g/L at `-20^@C` and 2.5 atm. What are the empirical and molecular formula of the gas

Explanation

To find the empirical and molecular formula of the gas composed of 30.4% nitrogen (N) and 69.6% oxygen (O), we will follow these steps:

### Step 1: Calculate the moles of nitrogen and oxygen.
Assume we have a 100 g sample of the gas.

- Moles of nitrogen (N):
\[
\text{Moles of N} = \frac{30.4 \, \text{g}}{14.01 \, \text{g/mol}} \approx 2.17 \, \text{moles}
