Platinum is a precious metal that is used as a catalyst for many important industrial reactions. Platinum can be purified by reacting platinum$($IV$)$ bromide solution with aluminium metal. To test this purification process, a student reacted $14\mathrm{.}3kg$ of aluminium metal with excess platinum$($IV$)$ bromide solution, After the reaction was complete, the student had extracted $75\mathrm{.}4kg$ of platinum metal. From this data, calculate the percent error of this experiment. Hint: Write a balanced chemical reaction equation and calculate the theoretical yield of platinum first.
