Butane gas, C4H10, is sold to campers as bottled fuel. Its density at 25 degrees Celsius and 1 atm is 2.38 grams per liter. what volume of butane gas at 25 degrees Celsius and 1 atm is required to heat one gallon of water from 25 degrees Celsius to 98 degrees Celsius? The reaction for combustion of butane (Delta H= -125.6 kJ/mol) is C4H10(g)+ 13/2 O2(g) ---> 4CO2(g) +5H20(g)
