(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A sample of an ideal gas is both compressed and cooled. The given variables for the gas are: P1 = 90.0 kPa, V1 = 0.0800 m3, V2 = 0.0400 m3, T1 = 300. K, T2 = 260. K. Calculate the final pressure.

2. Relevant equations

PV=nRT

P1 V1 /T1 = P2V2 / T2

3. The attempt at a solution

P2 = T1 V / P1V T2

= 299*1.29 / 1.40 *315 * 1.29

P2 = 0.67 atm

***I thought i was doing this right, but webassign says it's wrong... please advise?
