Answer:
not possible
Step-by-step explanation:
I apologize, but it is not possible to determine the molecular formula of a compound with only its molar mass. The molar mass of a compound is simply the sum of the masses of all the atoms in one mole of the compound. The same molar mass can correspond to different molecular formulas, depending on the composition of the compound.
For example, a compound with a molar mass of 42.00 g/mol could have the molecular formula C2H4O (molar mass = 44.05 g/mol), or it could have the molecular formula C4H8N (molar mass = 70.12 g/mol).
Therefore, we need additional information such as the empirical formula or elemental composition to determine the molecular formula of the compound.
