You are right and the answer is wrong. The average energy needs to be multiplied by Avogadro's number. "Typical" velocity is not...

Yes. I see now that you had this result in post #1 when you wrote down "So 2E5 = rho*g*h." There is no flaw in your understanding.

I am uncertain if this represents situation (a) or situation (b). i.e. is 2 = E-iR or is 2 = E? Or is the question ambiguous? Thanks!
