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....

  3. 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.

  4. The question is calculate the average kinetic energy of CH4 molecules in a sample of CH4 gas at 263K. What formula should i use when you say "use temp"
