Ionization Energy of the H-Atom

The Energy of the H-atom's single electron, when bound to the nucleus, is given by the formula
En = - R/n2

(Equation 1-4, page 8, "Physical Chemistry, A Modern Introduction", by Clifford E. Dykstra).
The lowest energy state corresponds to n=1. The electron is unbound when n is infinite. Calculate the energy of the ionizing the H-atom, i.e., the energy to take the system from n=1 to n=infinity. Assume that the Rydberg constant is 13.6 electron volts, and report your answer in electron volts.

Choose your answer in scientific notation, i.e., ± x.yzE{± ab}, and then press the 'Submit the above answer' button (below).
