Problem

A sealed cylinder contains

0.40\,\text{mol}

of neon gas at a pressure of

1.2\,\text{atm}

and a temperature of

25^{\circ}\text{C}

. Calculate the volume occupied by the gas.

Intuitive explanation

This is an ideal gas law problem—you're using the relationship between pressure, volume, amount, and temperature to find a missing variable. The key insight is recognizing that neon behaves as an ideal gas under these normal conditions, so you can apply $PV = nRT$ directly. Just make sure to convert temperature to Kelvin and use a gas constant with units matching your pressure (atm) and volume (L).
