In a common chemistry experiment, copper metal is converted to copper(II) nitrate by dissolving it in nitric acid; the other products are water and NO gas. The copper(II) nitrate is converted to copper(II) hydroxide by addition of aqueous sodium hydroxide. The copper(II) hydroxide is then converted to copper(II) oxide by intense heating; the other product is water vapor. The copper(II) oxide is converted back to copper metal by heating the oxide in a stream of hydrogen gas; the other product is water. Suppose you start the experiment with 1 gram of copper metal. How many grams of copper(II) oxide are expected to be collected when copper(II) hydroxide is heated? How many grams of copper metal was recovered in the last step if the overall yield is 64%?
