When 1 [g] of Hydrogen is combined with 8 [g] of oxygen, water (H2O) is formed and 3 · 105 [J] of energy are released.
(a) Determine the amount of water formed.
(b) If a household consumes an average of 2.5 [GJ] per month (Giga = 109), determine how much mass
it would be necessary to transform into energy to cover that consumption.
