To get the molecular formula, you must divide the molar mass of the empirical formula into the given molecular formula mass to find the multiplier. Then multiply that number by the EF to get the MF. To complete this quiz, you must have a periodic table and a calculator.

Solution Step #2: Divide the molecular weight (a standard term in chemistry) by the "empirical formula weight" (a nonstandard term): 78 / 13 = 6. Solution Step #3: Multiply the empirical formula (CH in this example) by the answer to step #2. This is the molecular formula: CH x 6 = C6H6. Problem #2: Many compounds have the empirical formula of CH2O.
