A sample of ideal gas at room temperature occupies a volume

Q1A sample of ideal gas at room temperature occupies a volume of 25.0 L at a pressure of 452 torr. If the pressure changes to 2260 torr with no change in the temperature or moles of gas what is the new volume V2?Q2If the volume of the original sample in Part A (P1 = 452 torr V1 = 25.0 L ) changes to 53.0 L without a change in the temperature or moles of gas molecules what is the new pressure P2?
