Suppose a fuel-cell generator was used to produce electricity for a house. If each H2 molecule produces 2e- how many kilograms of hydrogen would be required to generate the electricity needed for a typical house? Assume the home uses about 850 kWh of electricity per month, which corresponds to approximately 2.65 x 10^4 mol of electrons at the voltage of a fuel cell.
