Hello, im a newbie here but not new to chemistry, can you help with this question?

Calculate the final temp of a sample of Carbon dioxide of mass 16.0g that is expanded reversibly and adiabatically from 500cm^3 at 298.15K to 2.00dm^3.

So... first i would use Tf = Ti(Vi/Vf)^1/c

and c = Cv,m / R = Cp,m - R/ R

How do I solve for "Cp,m" value?

Thanks

Never mind then.

I figured it out. It is a value you can look up in a table.
