Hydrogen, a possible future fuel mentioned in Problem 1, can also be obtained from ethanol. Ethanol can be made from the fermentation of crops such as corn. How much hydrogen, in grams, could be obtained from 1.0 kg of ethanol (C2H5OH)?
Hydrogen is a possible future fuel. However, elemental hydrogen is rare, so it must be obtained from a hydrogen- containing compound such as water. If hydrogen were obtained from water, how much hydrogen, in grams, could be obtained from 1.0 L of water? (density of water = 1.0 g/cm3)
Molecular weight of ethanol =46 g
Molecular weight of hydrogen =1g
1 mole of ethanol=46 gms and it will give 6 gm of hydrogen
