Explanation The statement is shown below, The elemental analysis report gives the water vapor and a black solid compound that is 72 .3% Fe and 27 .7% O . Let consider mass of the compound is 100 g . Total Mass is calculated as follows, Mass of the compound = 100 g Fe = 72 .3% O = 27.7 % Molar mass of iron is 55 .845 g/mol , Molar mass of oxygen is 15.9988 g/mol . Moles of iron is calculated as follows, Moles of iron = 72.3 g Fe × 1 mol Fe 55.845 g Fe Moles of iron = 1.294 mol Moles of oxygen is calculated as follows, Moles of oxygen = 27 .7 g oxygen × 1 mol oxygen 15 .9988 g oxygen Moles of oxygen = 1.73 Moles Divide through by smallest number: Fe = 1.294 mol 1.294 mol = 1 Fe = 1 O = 1
