When butane (C4H10,58.14 g/mol) is burned in oxygen according to the reaction below,5755 kJ of heat is released.About how much butane should a backpacker carry if s/he needs to heat 1.50 L of water from 17°C to 100°C? Assume all the energy from the combustion is used to raise the water's temperature.[cp(water) = 4.18 J/(g . °C) ; d(water) = 1.00g/mL; cp(butane) = 1.69 J/(g . °C) ] 2 C4H10(g) + 13 O2(g) 8 CO2(g) + 10 H2O(
)
