I have a chemistry checkup today and I cannot seem to figure out how to get the answers. As I cannot seem to contact my teacher right now, I need some help here.

I need the PV product for gasses. I am going to use the first question as an example so I can figure out how to do the rest.

Ideal Gas 1 MW = 4 g/mol
Volume: 7.336L
Pressure: 1 atm

There is 0.3 mol of gas at a temperature of 298K. Can anybody help me with this one?

PV=nRT

(1atm)(7.336L)=(0.3 mol)(0.08206 L atm/K mol) T

T=[(1atm)(7.336L)]/[(0.3 mol)(0.08206 L atm/K mol)]= 297.9933 K  ~ 298 K
