In an experiment, `1.288g` of copper oxide was obtained from `1.03 g` of copper. In another experiment `3.672` g of copper oxide gave, on reduction, `2.938` g of copper. Show that these figures verify the law of constant proportions.

In an experiment, 4.90 g of copper oxide was obtained from 3.92 g of copper. In another experiment, 4.55 g of copper oxide gave, on reduction, 3.64 g of copper. Show with the help of calculation that these figures verify the law of constant proportions.

1.08 g of copper wire was allowed to react with nitric acid. The resulting solution was dried and ignited when 1.35 g of copper oxide was obtained. In another experiment 2.30 g of cpper oxide was heated in presence of hydrogen yielding 1.84 g of copper. Show that the above data in accordance with law of constant proporation.

How much copper can be obtained from 100g of copper sulphate ?

Weight of copper oxide obtained by heating 2.16 g of metallic copper with HNO_(3) and subsequent ingnition was 2.70 g In another experient, 1.15 g of copper oxide on reduction yielded 0.92 g of copper. Show that the results illustrance the law of definite proportions.
