(ii) Equal volumes of a solution of potassium carbonate were reacted separately with
an excess of dilute sulfuric acid solution.
Pure dry samples of potassium sulfate were obtained from the resulting solutions.
The experiment was repeated three times using the same conditions.
The masses of potassium sulfate obtained were
experiment 1 = 5.22g
experiment 2 = 5.24g
experiment 3 = 5.21 g
Calculate the mean mass of potassium sulfate obtained, giving your answer to
two decimal places.
