Adark brown binary compound contains oxygen and a metal. it is 13.38% oxygen by mass. heating it moderately drives off some of the oxygen and gives a red binary compound that is 9.334% oxygen by mass. strong heating drives off more oxygen and gives still another binary compound, which is only 7.168% oxygen by mass.
(a) compute the mass of oxygen that is combined with 1.000 g of the metal in each of these three oxides.
(b) assume that the empirical formula of the first compound is mo2 (where m represents the metal). give the empirical formulas of the second and third compounds.
(c) name the metal.
