Chapter 5, Problem 5P

Estimate the probability of finding an electron which is excited into the 2s orbital of the H atom, looking in a cubical box of volume $0.\text{75}\times \text{1}{0}^{-\text{36}}{\text{m}}^{\text{3}}$ centered at the nucleus. Then estimate the probability of finding the electron if you move the volume searched to a distance of 105.8 pm from the nucleus in the positive z direction. (Note that since these volumes are small, it does not matter whether the volume searched is cubical or spherical.)
