Consider a gas of hydrogen atoms...

a) At what temperature will an equal number of atoms have electrons in the ground (n=1) state and in the second (n=3) excited state?

b) At T=85400K when equal numbers of atoms are in the ground and first excited state (let that number be N), how many are in the second excited state?
