LP gas burns according to the following exothermic reaction: C3H8 (g) + 5 O2 (g) → 3 CO2 (g) + 4 H2O (g) ΔH°rxn = - 2044 ( kJ)
(a) What mass of LP gas is necessary to heat 1.6 L of water from room temperature 25.0°C to 100.0°C? Assume that during heating, 14% of the heat emitted by the LP gas combustion goes to heat the water. The rest is lost as heat to the surroundings.
