# A container has a volume of #18 L# and holds #15 mol# of gas. If the container is compressed such that its new volume is #8 L#, how many moles of gas must be released to maintain a constant temperature and pressure?

6.67 moles of gas must be released.

Avogadro's law can be used to find the solution:

The initial conditions are denoted by the number 1, and the final conditions are represented by the number 2.

Determine the factors that you know and don't know:

To find the final number of moles, reorder the equation as follows:

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- A container with a volume of #35 L# contains a gas with a temperature of #480^o K#. If the temperature of the gas changes to #300 ^o K# without any change in pressure, what must the container's new volume be?
- The gas inside of a container exerts #5 Pa# of pressure and is at a temperature of #190 ^o K#. If the pressure in the container changes to #32 Pa# with no change in the container's volume, what is the new temperature of the gas?
- A container with a volume of #4 L# contains a gas with a temperature of #270^o K#. If the temperature of the gas changes to #120^o K# without any change in pressure, what must the container's new volume be?
- What is an ideal gas, and what are its characteristics?
