`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.
