Asked by Rachel

Are there two ways of calculating the average kinetic energy of a molecule?

Ik that 1/2mv^2 works
but for this problem, i don't know the mass or the velocity....

instead of what?
Answered by bobpursley
average KE of a molecule is a function of temperature, that relation is in your book. The exact function depends on the type of molecule.
