Did you know?
Did you know that by analyzing the composition of an unknown compound, it is possible to determine its empirical formula and molecular formula? In the case of a compound containing 30.34% M and 60.56% O, with a molar mass of 92.00 g, the empirical formula can be found by converting the percentages into moles. With the molar mass of oxygen (O) being 16.0 g/mol and the molar mass of "M" being 14.1 g/mol, it can be determined that the compound has 2 moles of M and 3 moles of O. Therefore, the empirical formula is MO2. To find the molecular formula, the molar mass of the empirical formula needs to be compared to the molar mass of the compound. In this case, the molar mass of MO2 is 60.2 g/mol. As the molar mass of the compound is 92.00 g, it is determined that the molecular formula is M2O3.
