Problem 5 (20/100): Ethane is burnt to supply enough heat to convert 50 kg of water at 10 C to steam at 100 C. The heat of combustion of ethane is 368 kcal/mol. Specific heat capacity of water is 1 cal/(g C). Heat of vaporization of H2O is 540 cal/g. If 60% of the heat generated is utilized, calculate the required amount of ethane (in m) measured at STP.
