Calculate the ratio of the number of molecules in 2 L of oxygen and 8 L of nitrogen at STP.

Explanation

To solve the problem of calculating the ratio of the number of molecules in 2 L of oxygen (O₂) and 8 L of nitrogen (N₂) at STP, we can follow these steps:

### Step 1: Understand the conditions at STP
At Standard Temperature and Pressure (STP), 1 mole of any ideal gas occupies 22.4 liters. This means that we can use this volume to find the number of moles of gas in a given volume.

### Step 2: Calculate the number of moles of oxygen (O₂)
Given that we have 2 L of oxygen:
\[
