2B - % Yield calculations

    1)         3.924g of 2-chloropropane reacted with an excess of aqueous sodium hydroxide.

                2.955g of propan-2-ol was formed.  calculate the % yield of propan-2-ol.

    2)         Ethanol reacts with ethanoic acid to produce an ester and water.

                5.5g of the ester is produced from 4.0g of ethanol and 4.5g of ethanoic acid.

                calculate the % yield of the ester.
