How to determine empherical formula?

• Find the % by weight of each element present in 1 molecule of the compound
• The % weight should be then devided by atmoic weight.
• This gives the atomic ratio of elements present in compound.
• Then find the simplest ratio of atoms.
• If the value of simplest ratio is fractional then find the value to nearest whole number.

Relation between molecular and empherical formula :

Molecular formula = n× Empherical Formula

(n= any natural number)
