More importantly, what is the process for finding this? This is probably one of those overly simple things that I am not seeing for some reason.

The kinetic energy is given E =1/2 mv^2 and for neon which can be considered as a monotamic molecule we have
E = (3/2 ) k T where k= 1.38* 10^-23J/ °K here T= 273 K
so very easy E = (3/2) *1.3810^(-23)*273 = 5.65 10^-21J
This above is your answer
Probem usually continues asking the (mean) velocity of the molecule
E =kT = (1/2) m v^2 and v^2 =2E/m
where m is the mass of the molecule which is atomic mass divided by Avogadro's number
here m = 20/6.0210^23 =3.32 10^-23g

the formula for to find KE of a gas is KE=3/2nRT
where n =no of moles
R=universal gas constant[0.0821 atm lit /mole kelvin
T=temp of gas in kelvin
therefore acc to formula the answer is 3/2*1*0.0821*273=33.61995

Neon doesn't make molecules. Trick question?
