Methanol, ethanol. and n–propanol are- three common

QUESTION:

Methanol, ethanol, and n-propanol are three common alcohols. When 1.00 g of each of these alcohols is burned in air, heat is liberated as shown by the following data: (a) methanol \(\left(\mathrm{CH}_{3} \mathrm{OH}\right)\), – 22.6 kJ; (b) ethanol \(\left(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}\right)\), -29.7 kJ; (c) n-propanol \(\left(\mathrm{C}_{3} \mathrm{H}_{7} \mathrm{OH}\right)\), -33.4 kJ. Calculate the heats of combustion of these alcohols in kJ/mol.
