Empirical Calculator. Formula Used: (i) atomic-ratio = (compound - percentage) / (atomic mass) (from periodic table) Where, atomic ratio - atoms of one kind to another kind. atomic mass - average mass of an atom of an element (in dalton). Empirical Formula is calculated by finding the lowset value from the above calculation.The empirical formula is the simplest whole-number ratio of atoms in a compound. The ratio of atoms is the same as the ratio of moles. So our job is to calculate the molar ratio of Mg to O. Mass of Mg = 0.297 g. Mass of magnesium oxide = mass of Mg + mass of O. 0.493 g = 0.297 g + mass of O. Mass of O = (0.493 - 0.297) g = 0.196 g.You can find all my A Level Chemistry videos fully indexed at https://www.freesciencelessons.co.uk/a-level-revision-videos/a-level-chemistry/In this video, w... 5.7 Determining Empirical and Molecular Formulas.
