A 500.0 mL gas sample at STP is compressed to a volume of 300.0 mL and the temperature is increased to 35.0°C. What is the new pressure of the gas in pascals?

1 answer

what are P and T (in °K) at STP?
PV=kT, so PV/T = k is constant
so just find the new P such that PV/T remains unchanged from at STP
