Platinum is a precious metal that is used as acatalyst for many important industrialreactions. Platinum can be purified by reactingplatinum(IV) bromide solution with aluminiummetal. To test this purification process, astudent reacted 15.0 kg of aluminium metalwith excess platinum(IV) bromide solution.After the reaction was complete, the studenthad extracted 75.4 kg of platinum metal. Fromthis data, calculate the percent error of thisexperiment.Hint: Write a balanced chemical reactionequation and calculate the theoretical yield ofplatinum first.Do not show your work in the space provided.Record only your final answer with the correctnumber of significant digits and the properunits.
