If a gaseous fuel mixture stored at 748 mmHg and 298 K contains only methane (CH4) and propane (C3H8). While 12.4 L of this fuel mixture is burned, it produces 768 kJ of heat. Explain what is the mole fraction of methane in the mixture? Presume that the water produced by the combustion is in the gaseous state.
