Your actual experimental percent of copper is probably different from the theoretical value. Assume that your experimental mass percentage of copper was 38.92%. Which of the following is the BEST explanation for why for this experiment and the experimental results we obtained? Some of the copper was accidentally poured out. The copper was still wet. We created mass in the experiment. A side reaction occured.
5 g of hydrated barium chloride is heated in a crucible until the mass of the sample no longer changes. The mass of the sample after heating is 4.26 g. Assume that the mass lost during the heating is solely due to the loss of water from the sample. What percentage of water was contained in the barium chloride hydrate?
