A H atom absorbs a photon with a wavelength of 9.50 × 10^1 nm. If the energy of the final state of the H atom was -8.72 × 10^(-20) J, calculate the energy of the initial state. Express answer in scientific notation

  • chemistry -

    delta E = hc/wavelength; solve for delta E.
    delta E = E1-E2
    dE = Efinal - Einitial
    Solve for Einitial.
