Question

Which shows the correct relationship between the molecular formula and the empirical formula for C2H10N2

Answer 1

molecular formula = 2 x empirical formula

Step-by-step explanation:

Answer 2

The correct answer is molecular formula = 2 x empirical formula

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.
