A 12.7 L sample of gas is under a pressure of 740 mm Hg at 20degrees C.
What will be the volume of the gas if the pressure increases to 1.00 atm and the temperature drops to 0 degrees C

Use (P1V1)/T1 = (P2V2)/T2
Don't forget to change T to Kelvin. 
Use the combined gas law:
P2V2/T2=P1V1/T1 temps in Kelvins
