+ Core Chemistry Skill: Using the Gas Law Relating Volume and Moles
20 of 50
I Review | Constants | Periodic Table
Avogadro's law states that the volume, V, of a gas is
directly related to the number of moles, n, of the gas
when temperature and pressure are constant: (Figure 1)

where Vi is the volume filled by nj moles and V2 is the
volume filled by a different number of moles, n2.
Part B
A sample of gas in a cylinder as in the example in Part A has an initial volume of 54.0 L , and you have determined that it contains 1.80
moles of gas. The next day you notice that some of the gas has leaked out. The pressure and temperature remain the same, but the
volume has changed to 13.5 L. How many moles of gas (n2) remain in the cylinder?
