Recap - Fuel Value

Part of the Energy, Rates and Equilibrium section of Coddy's Chemistry journey. Lesson 10 of 35.

Challenge

A spirit burner holds ethanol, C₂H₅OH ( $46\ \mathrm{g/mol}$ ), which burns with $\Delta H = -1367\ \mathrm{kJ/mol}$ . During an experiment $23\ \mathrm{g}$ of ethanol burns. What is the heat change $Q$ ?
