Homework Help: Chem Ideal Gas Law

Posted by Julie on Thursday, November 1, 2012 at 6:58pm.

A 1.05 g sample of an ideal gas occupies 1.045 L at 20.0°C and 0.975 atm. What will be its volume at -8.6°C and 0.5 atm?
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?
