Empirical and molecular formula are calculated. Concept Introduction: Empirical formula of a chemical compound is the simplest ratio of the atoms present in it. It is calculated as; Start with number of grams of each element given. If percentages are given, then assume total mass is 100 g so that mass of each element is equal to percent given. Convert the mass to moles using their respective molar mass Divide each mole by smallest number of moles calculated Round off to whole number. This will give the simplest ratio from where empirical formula is derived. Molecular formula is calculated using molar mass and empirical formula mass To determine: Determine the empirical and molecular formula of the acid.
