Mass percentages of the the elements in the compound is the only additional information needed to calculate the empirical formula of a compound if the masses of each element of the compound are provided.
What is Empirical Formula ?
The Empirical formula is the simplest whole number ratio of atoms present in given compound.
What is Molecular formula of Compound ?
Molecular Formula = Empirical Formula × n
n = [tex]\frac{\text{Molar Mass}}{\text{Empirical Formula weight}}[/tex]
Thus from the above conclusion we can say that Mass percentages of the the elements in the compound is the only additional information needed to calculate the empirical formula of a compound if the masses of each element of the compound are provided.
