Which shows the correct relationship between the molecular formula and the empirical formula for c2h10n2?

The given compound C2H10N2 is the molecular formula because the ratios of the elements are not reduced into lowest terms (empirical formula). To get the empirical formula, the ratios must be reduced to the smallest possible integral ratio which gives CH5N. As a result, the ratio between both formulas is 2.

A Explanation:

Answer : The correct relationship between the molecular formula and the empirical formula is, Explanation : Empirical formula : It is the simplest form of the chemical formula which depicts the whole number of atoms of each element present in the compound.   Molecular formula : it is the chemical formula which depicts the actual number of atoms of each element present in the compound.   For determining the molecular formula, we need to determine the valency which is multiplied by each element to get the molecular formula. The equation used to calculate the valency is : As we are given that the empirical formula of a compound is . Thus, the molecular formula will be,

Answer 6

Molecular formula = empirical formula * n

Answer 7

The given compound C2H10N2 is the molecular formula because the ratios of the elements are not reduced into lowest terms (empirical formula). To get the empirical formula, the ratios must be reduced to the smallest possible integral ratio which gives CH5N. As a result, the ratio between both formulas is 2.
