A dark brown binary compound contains oxygen and ametal. It is 13.38% oxygen by mass. Heating it moderatelydrives off some of the oxygen and gives a red binary compound that is 9.334% oxygen by mass. Strong heatingdrives 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 with1.000 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

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
