A D-cell of the type utilized in flashlights can supply a half mole of electrons to an external circuit before all of its stored chemical energy has been dissipated. (One mole =6.02*1023 particle,) If this cell is connected to a small lamp of the kind used in our second lab experiment, the electron current in the bulb will be 2.40*1018 electrons per second. Compute the number of hours the bulb will remain lit.
