Problem

A gaseous fuel mixture stored at 748 mmHg and 298 K contains only methane (CH4) and propane (C3H8). When 12.1 L of this fuel mixture is burned, it produces 771 kJ of heat. What is the mole fraction of methane in the mixture? (Assume that the water produced by the combustion is in the gaseous state.)
