Empirical formula represents the simple whole number ratio of various atoms present in a compound. Give the relationship between empirical formula and molecular formula.

A compound contains 80% of carbon and 20% hydrogen. If the molecular mass is 30 calculate empirical formula and molecular formula.

Give one example each of a molecule in which the empirical and molecular formulae are: Same

Give one example each of a molecule in which the empirical and molecular formulae are: Different

Give an example of molecule in which. (i) Ratio of molecular formula and empirical formula is 6: 1 (ii) Molecular weight is 2 times of the empirical formula weight. (iii) The empirical formula is CH_2O and ratio of molecular formula weight and empirical fórmula weight is 6 .

How is molecular formula different from the empirical formula?

The molar mass of an organic compound is 120. A probable empirical formula of the compound is

There are compounds with same molecular formula but different structural formula. Write two compounds with different structural formula and the molecular formula C_3H_8O .
