The heat of combustion of methane is 213 kcal/mol. How many kcal of energy are released when 7.5 moles of CH₄ burns in an excess of oxygen gas?
CH₄ + 2O₂ $\rightarrow$ CO₂ + 2H₂O

Question

The heat of combustion of methane is 213 kcal/mol. How many kcal of energy are released when 7.5 moles of CH₄ burns in an excess of oxygen gas? CH₄ + 2O₂ $\rightarrow$CO₂ + 2H₂O

Quizplus · Accepted Answer

The energy released is calculated by multiplying the heat of combustion per mole by the number of moles: 213 kcal/mol * 7.5 mol = 1597.5 kcal, which rounds to 1600 kcal.
