Question

Suppose a fuel-cell generator was used to produce electricity for a
house. If eachH2molecule 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 of electrons at the voltage of a fuel
cell. 2.65*104

SOLUTION:
Each H2 molecule produces 2e- 
 
1 mole of H2 produces 2 moles of e- 
 
1 mole of H2 = 2 grams 
 
So, 2 grams of H2 produces 2 moles of electrons 
 
1 gram of H2 produces 1 mole of electron 
 
2.
