Which equation/law would you use to solve the following question:

A gas that has a pressure of 2 atm and a volume of 10 L. What would be the new volume if the pressure was changed to 1 atm?

• P1/T1 = P2/T2

• P1V1 = P2V2

• V1/n1 = V2/n2

• PV = nRT

Which equation/law would you use to solve the following question:

A sample of a gas has a volume of 852 mL at 298 K. What temperature is necessary for the gas to have a volume of 945 mL?
