The gas reached a pressure of 2.5 atm.

Since the volume is constant but the pressure and temperature are changing, this is an example of **Gay-Lussac's Law**:

#color(blue)(bar(ul(|color(white)(a/a) P_1/T_1=P_2/T_2color(white)(a/a)|)))" "#

We can rearrange the above formula to get

#P_2=P_1 × T_2/T_1#

Your data are:

The new pressure is 2.5 atm.
