Need an answer check...A gas has a volume of 269 mL at STP. Wht Celsius temperature will cause the gas to have a volume of 190 mL at a pressure of 182 kPa?
P1V1T2 = P2V2T1

Ziggle, thats what i got to so thanks. Scarlet, your equation is right but if multiply both sides by T1 and both sides by T2 iw works out to what i stated, its the same equation. And Thanks Ron i knew how to do the problem, I just wanted to know if I was right.

I got 346.5 K or 73.4 C. Compare that with your result.

Actually, the expressions is slightly wrong.
The Combined gas law is:
(P1V1)/T1 = (P2V2)/T2
Temperature should be in Kelvin so you don't divide by zero if temperature equals 0 degrees Celsius, which is very possible in real life.

You have the correct equation. Make sure to convert the temp. to Kelvin (add 273).
STP = 0 Celsius (273K) and 101.3 KPa.
Plug in the values and you get the new temp. in Kelvin.
Subtract 273 and you have your answer in oC
