Science - Charles' Law problem?

Ok, the formula for this would be V1P1T2=V2P2T1 The first volume (440) times the first pressure(102.4) times the 2nd temp( 303Kelvin) = the 2nd volume(X) times the 2nd pressure(102.4) times the 1st temp(298Kelvin) For the Temps you need to have them in kelvin otherwise the problem won't work. (You add 273 to go from C to Kelvin) if i did this right you should get 447.38. I hope this helps!!! Good luck!
