This is impossible. In order to find this you must know the elements in the compound


What is molecular mass?

the relative molecular mass or molecular weight of a compound is the mass of a molecule of the compound relative to the mass of a carbon atom taken as exactly 12.


How to calculate Molecular formula from empirical formula?

If you know the molar mass of the compound, you have to calculate the mass of the empirical formula and divide the molar mass of the compound by the mass of the empirical formula in order to find the ratio between the molecular formula and the empirical formula. Then multiply all the atoms by this ratio to find the molecular formula!


How do you find the molecular mass of a substance?

To find the molecular weight (also called the molecular mass or molar mass) of a compound or chemical, you need two things: the molecular formula of the compound and a periodic table. The molecular formula tells you how many atoms of each element is present in the compound. To find the molecular weight, just add up the atomic weights of each element present in the compound, being sure to multiply by the number of times that atom appears. The atomic weight of each element is found on a periodic table.
