In order to go from the empirical formula to the molecular formula, follow these steps: Calculate the empirical formula mass (EFM), which is simply the molar mass represented by the empirical formula. Divide the molar mass of the compound by the empirical formula mass. The result should be a whole number or very close to a whole number. Multiply all the subscripts in the empirical formula by the whole number found in step 2. The result is the molecular formula.

Calculate the empirical formula mass (EFM), which is simply the molar mass represented by the empirical formula.

Divide the molar mass of the compound by the empirical formula mass. The result should be a whole number or very close to a whole number.

WEBThus, it would appear that our empirical formula is essentially one half the mass of the actual molecular mass. If we multiplied our empirical formula by '2', then the molecular mass would be correct. Thus, the actual chemical formula is: 2* C 3 H 4 O 3 = C 6 H 8 O 6

WEBSo the empirical formula tells you what people have observed, maybe before they even knew that there was such a thing as atoms. What they would've observed is the ratio of the atoms to one another in a molecule without knowing in the exact molecule how many of that atom there are.
