A student heated 1.0L of ethanol (density 0.789 g/L) with 1.0 mL ethanoic acid (density 1.049 g/mL) with a sulfiric acid catalyst and noticed a vinegar-like smell to the product as well as a fruity medicinal smell. They isolated the ester product they made and weighed it and found that its mass was 0.943 g. Explain these results as best as you can.
