In this video we’ll work a practice problem for the Ideal Gas Law, PV=nRT. For this problem you can rearrange the equation to get T by itself to start with or just plug in values and solve for T.

1. Given values:
Pressure (P) = 2.0 atm
Volume (V) = 3.0 L
Number of moles (n) = 0.5 moles
Ideal gas constant (R) = 0.0821 L·atm/(mol·K)

2. Use the ideal gas law equation: T = PV / (nR)

3. Plug in the values: T = (2.0 atm * 3.0 L) / (0.5 mol * 0.0821 L·atm/(mol·K))

4. Calculate: T = 6.0 / 0.04105

5. T = 146 K
