E = 2.180E-18(1/2^2 - 1/0)
the right answer is 2.42x10^-19J. but once i plug the numbers on my calculator i get an error message.
You got an error message because 1/0 is an indeterminate. I didn't know how to write 1/infinity but that's what it should have been and 1/infinity is 0. As to the other, I guess I don't know what the second excited state is. I assumed it was with the electron in n = 2; I guess that is right so I don't know what second excited state means.
