      Find the molecular formula of a compound if its empirical formula is CH2O and its molar mass is 90 g/mol. CH2O = 12 + (2 x 1) + 16 = 30 g/mol. 90/30 = 3, so empirical formula x 3 + molecular formula =m so MF = C3H6O3 _____ Title: UNIT 3 – WORKSHEET 1: MOLE PROBLEMS Author: Fairfax County Public Schools Last modified by ...
