In a diesel engine, the piston compresses air at 302 K to a volume that is 0.0628 of the original volume and a pressure that is 48.2 times the original pressure. What is the temperature of the air after the compression?

I know pv = nRT, but I don't know how to use this fromula because the problem doesn't have anything to do with moles. Is there aother formula I dhould be using.
