We are asked how much heat is emitted
Since the gas are under the same conditions, the volume percent is the same as the mole percent.
Calculate total moles:
n = 0.0617 mol
Calculate moles of each:
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.)
