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 14.6 kg of aluminium metal with excess platinum(IV) bromide solution. After the reaction was complete, the student had extracted 75.4 kg 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. Do not show your work in the space provided. Record only your final answer with the correct number of significant digits and the proper units. Answer: Evaluate your calculated percent error, is this an acceptable percent error?
