Solution

In $2$ different experiments, copper oxide was obtained from copper and the ratio of mass of $C u$ and mass of $O$ found in $2$ experiments are same, i.e $4 : 1$
This shows that the experiments are in accordance with the law of constant or definite proportions. According to this law, a chemical compound always contains exactly the same proportion of elements by mass.
