Empirical Formula and Its Determination
Empirical Formula
A chemical formula which shows the simplest whole number ratio between the atoms of different elements present in a compound is called empirical formula.
Examples
Steps Involved in Determination of Empirical Formula
Following steps are involved in determination of empirical formula.
(i) Determination of Percentage Composition
(ii) Finding the Number of Gram Atoms of Each Element
(iii) Determination of the Atomic Ratio of Each Element
(iv) If the atomic ratio is simple whole number, it gives the empirical formula, otherwise multiply with a suitable digit to get the whole number atomic ratio.
