Solution:
Consider the following thermochemical equation for the combustion of acetone (C3H6O), the main ingredient in nail polish remover: C3H6O(l) + 4 O2(g) → 3 CO2(g) + 3 H2O(g), ΔH˚rxn = -1790 kJ. If a bottle of nail polish remover contains 177 mL of acetone, how much heat would be released by its complete combustion? The density of acetone is 0.788 g/mL.
