Question

A gas sample collected at 35.0°C and a pressure of 710 torr has a volume of 200 mL. The temperature and pressure are changed, and the gas is compressed to 150 mL. The new temperature is 40.0°C; what is the new pressure?

Gas laws: 

V1P1 = V2P2

V1T2 = V2T1

V1P1T2 = V2P2T1

?1?1=?2?2V1n1=V2n2

??=???(?=0.0821?⋅??????⋅?)PV=nRT(R=0.0821L⋅atmmol⋅K)
