An ideal monatomic gas, consisting of 2.47 mol of volume 0.0890 m^3, expands adiabatically. The initial and final temperatures are 22.3oC and -64.3oC. What is the final volume of the gas(adsbygoogle = window.adsbygoogle || []).push({});

According to a formula in the book, the volume of an ideal monatomic gas' volume expands by 1.52, but I think I am misinterpreting that. Anyway, I have tried using the formula

V2/ V1 = (P1/P2)^y -- but I don't know how to get the second pressure. Any help would be appreciated.
