Answer:
final pressure would be p2 = 10.833 atm
Explanation:
If the gas has constant temperature then pressure×volume = constant.
let the initial pressure and volume be p1, v1
and final pressure and volume be p2, v2.
therefore [tex]p1\times v1=p2\times v2[/tex]
[tex]2.5\times 6.5 = p2\times 1.5[/tex]
therefore final pressure would be p2 = 10.833 atm
