Hydrogren, a possible future fuel, can also be obtained from other compounds such as ethanol. Ethanol can be made from the fermentation of crops, such as corn. How much hydrogen in grams can be obtained from 1.0 kg of ethanol (C2H5OH)?

2CH3CH2OH + 2Na Би 2CH3CH2ONa + H2

so if it is obtained from the reaction with a metal then.

1.0kg((1000g/kg)(1mol ethanol/46.06844g)(1mol H2/2mol ethanol)(2.01588g/mol H2)=________g H
