E. A certain compound with a molecular mass of 174 g/mol has been found to consist of 41.4% C, 3.4% H, and 55.2% O by mass. (1) Determine the empirical formula of the compound. (2) Find the mass of 1 empirical unit: the "empirical" mass of 1 mole of the compound based on the empirical formula. (3) Determine the molecular formula of the compound by (a) dividing the molecular mass by the mass of 1 empirical unit from (2) and (b) multiplying the empirical formula by the answer obtained from (a).
