Molecular Formula
Some Basic Concept Of Chemistry of Class 11
Molecular Formula
The formula which represents the actual number of each individual atom in any molecule is known as molecular formula.
For certain compounds the molecular formula and the empirical formula may be same.
Molecular formula = (Empirical formula)n
Molecular weight = Empirical formula weight x n
If the vapour density of the substance is known, its molecular weight can be calculated by using the equation.
2 x Vapour density = Molecular weight
