**DrBob222**, Monday, November 21, 2011 at 2:24pm(P1V1/T1) = (P2V2/T2) which I've rearranged to

(P1V1T2) + (P2V2T1)

P1 = 1 atm

V1 = 1L

T1 = 273K

P2 = 2.00 atm

V2 = 10.0L

T2 = ?

(1*1*T2) = (2.00*10.0*273) = about 5460K

Another thought. Did you remember to use T in Kelvin?

Last thought. Did you remember to convert 5460 K back to C (the problems asks for C). That will be 5460-273 = 5187. Check my work.
