A sample of green copper(II) carbonate is heated strongly in a boiling tube until the thermal decomposition is complete and only a black residue of copper(II) oxide remains.
The actual mass of copper(II) oxide obtained is 4.14 g.
The theoretical yield of copper(II) oxide for this reaction is 4.50 g.
Calculate the percentage yield of copper(II) oxide.
