Final answer:To find the mass percent of oxygen in chromium(III) carbonate, calculate the percentage based on the compound's molecular weight and the number of oxygen atoms present.Explanation:To calculate the mass percent of oxygen in chromium(III) carbonate (Cr2(CO3)3), you need to consider the molecular weight of oxygen in the compound. In this case, the compound contains 3 oxygen atoms. The formula weight of Cr2(CO3)3 is 291.01 g/mol. The mass percent of oxygen can be calculated as follows:Calculate the molar mass of oxygen in the compound: (3 x 16.00 g/mol) / 291.01 g/mol x 100% = 15.60%Therefore, the mass percent of oxygen in chromium(III) carbonate is approximately 15.60%....
