calculation of Empirical and Molecular Formula
The empirical formula of a Compound is calculated from the percentage Composition of compound as follows
The percentage of each element is divided by its atomic weight to get the relative number of atoms of various elements present in the compound .
The relative number of atoms is divided by the minimum value to have the simplest ratio of the number of atoms .
If the simplest ratio is not a whole number then it is made a whole number by either changing the value to the nearest whole number or by multiplying with a suitable integer throughout .
The whole number is written as a subscript at the lower right hand corner of the symbol of the element to give the empirical formula .
The empirical formula weight is calculated by adding the atomic weight of atoms of all elements present in empirical formula .
The molecular weight of the compound is calculated from the given data .
' n ' is calculated by using the relation
molecular formula = emperical formula × n
