Question

Please help with A and B:

Part A

A sample of ideal gas at room temperature occupies a volume of 27.0 L at a pressure of 352 torr . If the pressure changes to 1760 torr , with no change in the temperature or moles of gas, what is the new volume, V2?

Express your answer with the appropriate units.

Part B

If the volume of the original sample in Part A (P1 = 352 torr , V1 = 27.0 L ) changes to 69.0 L , without a change in the temperature or moles of gas molecules, what is the new pressure, P2?

Express your answer with the appropriate units.

Explanation / Answer

Part A:

According to Boyle's law:

P1/P2 = V2/V1

P1 = 352torr

V1 = 27L

P2 = 1760torr

V2 =?

P1/P2 = V1/V2

V2 = P1V1/P2

V2 = 352*27/1760

V2 =5.4L

Part B:

P1/P2 = V2/V1

P1 = 352torr

V1 = 27.0L

V2 = 69.0L

P2 = ?

P2 = P1V1/V2

P2 = 352*27.0/69.0

P2 = 137.7torr
