- You are given a mixturc of CUCO, and CuO. You place the mixturcina crucible and heat it to decompose the CUCO; into CO, gas and CuO. You made sure that the CUCO, had completely decomposed by constantly heating it, cooling it, and weighing it until the mass remains the same. Using the data below from the experiment, calculate the % CUCO; in the original sample. Mass of empty crucible: 22.107 g Mass of crucible + sample beforc heating: 23.152 g Mass of crucible + sample at constant mass: 22.845g Please do not include units in your answer and use proper sig figs.
