1.	In 1811, Avogadro calculated the formula of camphor by means of elemental chemical analysis and by measuring the density of its vapour. Avogadro found the density to be 3.84 g/L when he made the measurement at 210^(@)C at 1 atm pressure. Which of the following is the correct formula of camphor?
Answer» `C_(10)H_(14)O` `C_(10)H_(16)O` `C_(10)H_(16)O_(2)` `C_(10)H_(18)O` SOLUTION :`Pm=DRT` `m=(dRT)/(P)=(3.84xx0.0821xx483)/(1)=152.27` `therefore C_(10)H_(10)O` will be the CORRECT formula.
