When $2.16 \ g$ of metallic copper is treated with nitric acid,the weight of copper oxide obtained is $2.70 \ g$. In a second experiment,$1.15 \ g$ of copper oxide on reduction gives $0.92 \ g$ of copper. These results illustrate the law of:
- AEquivalent Proportions
- BMultiple Proportions
- CDefinite Proportions
- DConservation of Mass
