Solution: A gaseous fuel mixture contains 23.1% methane (CH4), 41.1% ethane (C2H6) and the rest propane (C3H8) by volume.When the fuel mixture contained in a 1.53 L tank, stored at 751 mmHg and 298 K, undergo

A gaseous fuel mixture contains 23.1% methane (CH₄), 41.1% ethane (C₂H₆) and the rest propane (C₃H₈) by volume.

When the fuel mixture contained in a 1.53 L tank, stored at 751 mmHg and 298 K, undergoes complete combustion, how much heat is emitted? (Assume that the water produced by the combustion is in the gaseous state.)
