5 hours ago To use this online calculator for Molecular Formula, enter Molar Mass (M) & Mass of Empirical Formulas (EFM) and hit the calculate button. Here is how the Molecular Formula calculation can be explained with given input values -> 2442.286 = 0.04401/1.802E-05.

1. C: (43g/12g/mole) x 0.40 = 1.43moles
2. H: (43g/1g/mole) x 0.067 = 2.88moles
3. O: (43g/16g/mole) x 0.533 = 1.43moles
4. C1.43H2.88O1.43 / each by 1.43
5. CH2O = 12 + 2 + 16 = 30g/mole
6. Then 180/30 = 6
7. x #5 above by 6 (#5 above)
8. C6H12O6 = 6 x 12 + 12 x 1 + 6 x 16 = 72 + 12 + 96 = 180
9. empirical is #4 and molecular is #8
10. Calculate the empirical formula mass. You determine this number by finding the mass of HO (1 hydrogen atom and 1 oxygen atom).
11. Divide the gram molecular mass by the empirical formula mass. Dividing the gram molecular mass by this value yields the following:
12. Multiply each of the subscripts within the empirical formula by the number calculated in Step 2.
