Jill performs the electroplating experiment and calculates the theoretical mass of copper to be plated as 1.798 g. She weighed the brass disc (which was plated in the experiment) before and after the electroplating process: mass of disc before = 2.118 g mass of disc after = 3.183 g What was the percent yield of Jill's electroplating process? Recall, % yield = actual/theoretical x 100%. Report your response to one digit after the decimal.
