1.375 g of cupric oxide was reduced by heating in a current of hydrogen and the mass of copper that remained was 1.098 g . In another experiment 1.179 g copper was dissolved in nitric acid and the resulting copper nitrate was converted into cupric oxide . The mass of cupric oxide formed was 1.476 g . Show that these results illustrate the law of constant composition.
