CHEM101: General Chemistry I

We use the Ideal Gas Law PV = nRT – where P is pressure, V is volume, n is the number of moles, T is temperature, and R is the gas constant – to describe the relationship among pressure, volume, temperature, and the number of moles of a gas.

Watch these videos, which show how to solve for the different variables in an Ideal Gas Law problem. Pay attention to the units used for the variables in the Ideal Gas Law. It is necessary to use the proper units to ensure your units cancel when you complete an Ideal Gas Law problem.
