a) what is the its average velocity if the temperature is 300 K?

b) what is its average kinetic energy?

The average kinetic energy of a particle or molecule of any mass is

Eav = (3/2) k T

where k is the Boltzmann constant,

1.38^10^-23 J/K, and

T is the temperature in Kelvin

Once you have the average KE, get the average (actually, r.m.s) velocity from

(1/2) M V^2 = Eav

M is the particle mass
