Fantastic! Oxygen has mass and also occupies space. For example, when you inhale air, your lungs grow in size due to gases like oxygen.

Take two numbers, say \(5\) and \(6\). You can find a number between \(5\) and \(6\), say \(5.5\). Now, between \(5\) and \(5.5\), you can find \(5.25\). Between \(5\) and \(5.25\), you can find \(5.125\).

Can you

- No
- Depends on the numbers
