Question
1- What is the pressure in a 24.0 cylinder filled with 0.780 of nitrogen gas at a temperature of 305 ?2- What is the temperature of 0.420mol of gas at a pressure of 1.5atm and a volume of 12.2L ?
3-A cylinder with a moveable piston contains 180mL of nitrogen gas at a pressure of 1.02atm and a temperature of 308K.What must the final volume be for the pressure of the gas to be 1.32atm at a temperature of 365K ?
4- A bag of potato chips contains 580mL of air at 20.0 degrees celsius and a pressure of 775mmHG.
Assuming the bag does not break, what will be its volume at the top of a mountain where the pressure is 452mmHg and the temperature is 5.00 degrees celsius?
Explanation / Answer
1. PV=mRT; P=(.780*8.314*305)/24 2. PV=mRT T=(1.5*12.2)/(8.314*.42) 3. P1V1/T1=P2V2/T2 4. P1V1/T1=P2V2/T2
