I used PV=nRT for this. substituted P for 0.5 then n for 1.05, R .0821 then T for 264.4 K

After doing this I got .0219 but it is incorrect, what am I doing wrong?

- Chem Ideal Gas Law -
**bobpursley**, Thursday, November 1, 2012 at 8:45pmN is not 1.05, that is the mass in grams.

do this:

PV=nRT

PV/T=nR for ideal gasses, nR is a constant.

At the second conditions,

PV/T=nR Hmmm. One is lead immediatlely to the combined gas law

P1V1/T1=P2V2/T2

solve for V2
