Calculate the ratio of number of molecules in 10 L of `O_(2)` and 10 L of `N_(2)` at `25^(@)C` and 1 atm. State the law used in the calculation

Explanation

To solve the problem of calculating the ratio of the number of molecules in 10 L of \( O_2 \) and 10 L of \( N_2 \) at \( 25^\circ C \) and 1 atm, we can follow these steps:

### Step 1: Understand the conditions
We are given:
- Volume of \( O_2 = 10 \, L \)
- Volume of \( N_2 = 10 \, L \)
- Temperature = \( 25^\circ C \)
- Pressure = 1 atm
