Calcium and Magnesium carbonates occur together in the mineral dolomite. Suppose you heat a sample of the mineral to obtain the oxides,CaO and MgO, and then treat the oxide sample with HCl. If 7.695g of the oxide sample requires 125 mL of 2,55 M HCl, CaO(s) + 2 HCl(aq)--->CaCl2(aq) + H2)(l) MgO(s) + 2HCl(aq)--->MgCl2(aq) + H2O(l) What is the weight percent of of each oxide (CaO and MgO) in the sample?
