A particular atom has two energy levels with a transition wavelength of 420 nm. At 297 K

Question:

A particular atom has two energy levels with a transition wavelength of 420 nm. At 297 K there are 2.5 x 10²¹ atoms in the lower state.

(a) How many atoms are in the upper state?

(b) Suppose that 1.8 x 10²¹ of the atoms in the lower state are pumped to the upper state. How much energy could this system release in a single laser pulse?
