Question

If a bottle of nail polish remover contains 176 mL of acetone, how much heat would be released by its complete combustion? The density of acetone is 0.788 g/mL.

Answer 1

-) o Consider the combustión reaction 4c-8-ch, * 402) >30 +34,62 Here the enthalpy of combustion Hombustion = -1790.kl. mol there fore Mole of acetone = weight of Substancex density - Molecular weight = 176ml x 0.188 gmi = 2.38 78 mol Oy 58.08 g.mol = 2.9 mol So taken the product of mole gacetone and combustion per mol of reaction gives = - 1790 kJ. mol x 2.39 mol = 4278.1kJ heat will release.
