Which of the following statements regarding empirical and molecular formulas is CORRECTt?A. Information on percent composition is all that is necessary to determine both an empirical and a molecular formula. B. A compound with an empirical formula of CH2O and a molar mass of 90 g/mol would have a molecular formula of C3H6O3. C. The compounds C2H4 and C3H6 have different empirical formulas. D. The compound benzene has a molecular formula of C6H6, so its empirical formula would be C3H3. E. The formula Ca2Cl4 is the correct empirical formula for calcium chloride.
