    An electron is confined in an infinitely deep well of width 0.1nm, about the size of an atom. Estimate the energy of the ground state in eV.



    Is this the equation I should be using for this equation?

    E=(n^2 hbar^2 ∏^2)/(2m L^2)

    Yes, and since you are looking for the ground state, n just equals 1.
