(100g carbon / 12.011 g ) = 8.33 moles of carbon. Four times as many hydrogen atoms are needed as carbon atoms to make methane, , so four times as many moles will be required also: (4 moles H / 1 mole C) x 8.33 moles C = 33.3 moles of hydrogen. Since the atomic weight of hydrogen is 1.008, this corresponds to.
