2. A similar experiment is performed to determine the empirical formula of an oxide of copper, and the following data were collected. Predict the empirical formula of the copper oxide from these data. Mass of crucible, cover, and copper sample Mass of empty crucible with cover 21.53 g 19.66 g Mass of crucible and cover and sample (after heating) 21.76 g How can the experiment for the determination of the empirical formula of an oxide of copper be improved?
