A gas has a pressure of 2.96 atm when its
volume is 3.93 L. What will the pressure
be when the volume is changed to 1.09 L,
assuming constant temperature? Express the
ﬁnal pressure in torr.

• chemistry -

P1=2.96
P2=?
V1=3.93L
V2=1.09L

**** 1 atm = 760 torr

Use P1V1/T1=P2V2/T2 and solve for P2. Assuming T1=T2, you can ignore the T's and rewrite the equation as P1V1=P2V2.

Rearranging the equation results in (P1V1)/P2=V2

Plug in your values and solve for V2

Afterwards multiply by the conversion provided to get your answer in torr.
