Calculate the translational kinetic energy of O2 at
a) 300. K
b) 1000. K

Speed is not given. Do I need to find the average speed first?

The formula I'm using is
Ek= 1/2m v^2
I notice I'm not given mass in the problem either. Would I use molar mass?

You are on a tangent. You need to be using 3/2 kT
