The question is unfortunately incomplete. It cuts off in mid sentence with 'what?'
Presumably there is a temperature change, but that information didn't get included. (volume remains constant).
You could add the missing information using the 'Additional Details' area of your question screen if you wish.
However, I think you can use Gay-Lussac's Law to solve for final pressure (P2) .
(You have to convert the Celsius to Kelvin)
P1 = 319 mm Hg
T1 = 298 K .......................................... [ (25 + 273) = 298 ]
P2 = ?
T2 = ? (the missing information in the question)
Guy-Lussac's Law : (P1 / T1) = (P2 / T2)
Rearrange that to solve for P2 and put in the numbers :
P2 = [P1 x (T2 / T1)]
