An ideal gas is contained in a cylinder with a volume of 5.0 102 mL at a temperature of 30.°C and a pressure of 710. torr. The gas is then compressed to a volume of 27 mL, and the temperature is raised to 800.°C. What is the new pressure of the gas?

Change temps to kelvins

P2V2/T2=P1V1/T1

solve for P2

Change temps to kelvins

P2V2/T2=P1V1/T1

solve for P2

im confused on what numbers need to be plugged into the equation

Then write them down in columns
P1.....V1......P2.......V2....T1.....T2

then substitute into the equation.

okay so its (710)(500)/(303)=p2(27)/1073

then i multiply?

Yes, solve for P2. You multiply AND divide to do that.
