Using our Molecular Weight Calculator we can easily get 30.026 g/mol. Next, we divide the molecular weight of the substance under study by the just found molecular weight of the empirical formula and obtain: 180.16 / 30.026 = 5.954. After rounding this result to a whole number we have n = 6, and obtain the molecular formula of glucose: C 6 H 12.
