Can someone tell me if I did this combined gas law problem correctly?
What would happen to the volume of a container whose initial volume is 21.5 L at STP (standard pressure) and is introduced to conditions of 93.2 kPa and 333 K?
Formula: P1 x V1 / T1 = P2 x V2 / T2
V2 = P1 x V1 x T2 / P2 x T1
My work:
V1 = 21.5 L
T1 = 333 K
P1 = 93.2 kPa
T2 = 273 K
P2 = 101.3 kPa
V2 = 93.2 kPa x 21.5 L x 273 K 547037
------------------------------- = ________
101.3 kPa x 333 K 33732.9
Final Answer = 16.2167

No, you have the right formula and your algebra is right but you didn't assign the values correctly. You problem states you have 21.5L at STP so V1 is 21.5, T1 is 273 and P1 is 101.325. You are changing the conditions to 93.2 kPa so that is P2 and to temp of 333 K so that is T2.
