Effective mass

In a semiconductor where the bottom of the conduction band is at k = 0, an electron moves with a wavenumber k = 200000000 m-1. If the effective mass of electrons in the conduction band is 0.3 m, what is the energy of this electron measured from the bottom of the conduction band?

E = eV
