Question

1.375 g CuO was reduced by hydrogen and 1.098 g Cu was

obtained. In another experiment 1.178 g of Cu was dissolved

in nitric acid and the resulting copper nitrate was converted

into CuO by ignition. The weight of CuO formed was 1.476g.

Show that these results prove the law of constant

composition
plz do it fast with proper explanation​
