Although we do not have a complete description of a chemical reaction to look at, one can only assume that a process is being considered in which the $C {u}^{2 +}$ ion in $C u C {l}_{2}$ is being changed into copper metal.
Since a mole of $C u C {l}_{2}$ contains one mole of Cu atoms, for each one mole of copper chloride, you will obtain one mole of copper metal.
