Sample Problem:

An ideal gas occupying a 2.0 L flask at 760 torr is allowed to expand to a volume of 6,000 mL.

Calculate the final pressure in atm.

Let's solve Boyle's law for P_{2} and then substitute values for P_{1},
V_{1} and V_{2.}

Ooops! The units are torr-L/mL instead of atm. To fix this problem let's start by converting torr to atm.
