## Ideal Gases and the Ideal Gas Law

3 moles of an ideal gas fill a cubical box with a side length of 30cm. If the temperature of the gas is 20°C, what is the pressure inside the container?

Hydrogen gas behaves very much like an ideal gas. If you have a sample of Hydrogen gas with a volume of 1000 cm^{3 }at 30°C with a pressure of 1 × 10^{5} Pa, calculate how many hydrogen atoms (particles) there are in the sample.

## Solving Ideal Gas Problems With Changing States

A balloon contains 3900cm^{3} of a gas at a pressure of 101 kPa and a temperature of –9°C. If the balloon is warmed such that the temperature rises to 28°C, what volume will the gas occupy? Assume the pressure remains constant.
