23. A 32.3 L sample of a gas at 305oC and 1.20 atm is to be cooled at constant pressure until its volume becomes 28.4L. What will be the new gas temperature?

Tf = Vf*Ti/Vi

Tf =28.4L x (305+273)K / 32.3L

= (28.4)(578)K / 32.3

= 16415.2/32.3

Tf = 508K

I got this one wrong on a test please let me know what I'm doing wrong???
