(A) The energy of an electron in the $n^{th}$ orbit of a hydrogen atom is given by the formula: $E_n = \frac{-13.6}{n^2} \ eV$. Given that the ground state energy $(n=1)$ is $-13.6 \ eV$. For the energy level corresponding to the quantum number $n = 5$: $E_5 = \frac{-13.6}{5^2} \ eV$ $E_5 = \frac{-13.6}{25} \ eV$ $E_5 = -0.544 \ eV \approx -0.54 \ eV$.
