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?

Answer 1

(P1V1)/T1 = (P2V2)/T2
Remember T is in Kelvin.
I would use 1 atm for P1 so P2 will be in atm. Then convert to Pa.

Answer 2

456.0 pa

Answer 3

1.28

Answer 4

P1(V1)
---------- = ----------
T1

Answer 5

P1(V1) P2(V2) CrossMulti. 1atm(500.0mL) P2(300.0)
______ = ______ ------> _____________ = __________
T1 T2 273K

Answer 6

Working the Problem Out:
P1(V1) P2(V2) CrossMulti. 1atm(500.0mL) P2(300.0)
______ = ______ ------> _____________ = __________
T1 T2 273K 308K

Answer: 1.88atm
