Empirical formula is the simplest positive integer ratio of atoms present in a compound.
Ascorbic acid contains carbon , hydrogen and oxygen.
To get the empirical in this case we divide by the smallest value;
3.407/3.406 : 34.53/3.406 : 3.406/3.406
= 1 : 1.33 : 1
this is equivalent to; 1 : 4/3 : 1 , multiplying by 3
we get 3 : 4 : 3
Therefore the empirical formula will be C3H4O3
