You take three compounds consisting of two elements and decompose them. To determine the relative masses of X, Y, and Z, you collect and weigh the elements, obtaining the following data: a. What are the assumptions in solving this problem? b. What are the relative masses of X, Y, and Z? c. What are the chemical formulas of the three compounds? d. If you decompose 21 g of compound XY, how much of each element is present?
