I think I might be correct here: If anyone can confirm? Turns out I didn't really need to change any units just yet.
Cv = nRp/2
n=31.28moles/kg
Molecular mass = Mass/n = 1kg/31.28moles = 31.96g/mol.
I assume this would be Oxygen molecules.
Ok I just found the degrees of freedom.
Cp/Cv=1 + 2/P
7/5=1+2/P
P = 5 degrees of freedom.
Even though I'm still sure I have to change the units to find the Molar mass. I only found the degrees of freedom due to Cp/Cv is a ratio so units did not matter.
I have to somehow change the Cv and Cp...
Hey having a bit of trouble with this one. I really don't know how to start. Think I just simply don't have the right equations or I'm using the wrong units. Hopefully you guys can help me.
