Answer» u5.18 g of COPPER METAL is first converted into copper nitrate and subsequently on ignition to give 6.45 g of CuO. In another experiment, 1.10 g of copper GAVE 1.37 g of CuO. Show that these data illustrates the law of constant composition.Case I:Weight of metal (Cu) = 5.18 gWeight of metal oxide (CuO) = 6.45 gPercentage of Cu,Weight of Copper/Weight of CuO X 100%= 5.18/6.45 x 100%= 80.29%Case II:Weight of metal (Cu) = 1.10 gWeight of metal oxide (CuO) = 1.37 gPercentage of Cu,Weight of Coppe
