Worksheet 11.1 KEY Molar Mass Calculations A mole is a standard unit of measurement for amount of a substance. For an element, one mole is equivalent to the mass of that element as it is listed on the periodic table, and thus represents its molar mass. For a compound, one must take the sum of all elements in the compound with EMPIRICAL FORMULA & MOLECULAR FORMULA WORKSHEET 1. Find the molecular formula of a compound that has a molar mass of 26 g/mol, and has an empirical formula of CH. EF is CH, mass = 12 + 1 = 13 g/mol MF = n (EF) n = molar mass ÷ empirical mass, = 26 ÷ 13 = 2. So MF = C 2 H 2 2. Empirical and Molecular Formula Worksheet SHOW WORK ON A SEPARATE SHEET OF PAPER.
