When 5 litres of a gas mixture of methane and propane is perfectly combusted at 0°C and 1 atmosphere, 16 litres of oxygen at the same temperature and pressure is consumed. The amount of heat released from this combustion in kJ (ΔHcomb: CH₄(g) = 890 kJ mol⁻¹, ΔHcomb: C₃H₈(g) = 2220 kJ mol⁻¹) is:

A

38

B

317

C

477

D

32

Correct Answer

Option C

Detailed Explanation

The combustion reaction involves stoichiometry to determine the moles of methane and propane, and their respective heat of combustion is used to calculate the total heat released.
