Define empirical formula and molecular formula. Write the relationship
between empirical formula and molecular formula.
Answers
The formula which indicates the actual ratio of the atoms in a molecule/compound is molecular formula.The formula which indicates the simple ratio of the atoms in a molecule/compound is emperical formula.For example:Glucose=C6H1206,this is the molecular formula but if the numbers 6,12 and 6 are divided by a common multiple which is 6 to make the compound appear in its smallest form,it becomes CH2O.This is the emperical formula of the compound.
Answer:
Molecular formulas tell you how many atoms of each element are in a compound, and empirical formulas tell you the simplest or most reduced ratio of elements in a compound. If a compound's molecular formula cannot be reduced any more, then the empirical formula is the same as the molecular formula.
