Acetone (propanone), a clear liquid solvent with an acrid odor, is used to remove nail polish, paints, and resins. It has a low boiling point and is highly flammable. Acetone has a density of 0.786 g/mL and a heat of combustion of −1790 kJ/mol.(2.8, 7.2, 8.3, 8.4, 9.2, 9.5)
a. Draw the condensed structural formula for acetone.
b. What are the molecular formula and molar mass of acetone?
c. Write a balanced chemical equation for the complete combustion of acetone, including the heat of reaction.
d. Is the combustion of acetone an endothermic or exothermic reaction?
e. How much heat, in kilojoules, is released if 2.58 g of acetone reacts completely with oxygen?
f. How many grams of oxygen gas are needed to react with 15.0 mL of acetone?
