Ap chemistry worksheet 7 empirical and molecular formulas answers

  • Empirical Formula & Molecular Formula - There are two broad classes of the formula called Empirical formula & Molecular formula. The empirical formula shows the simplest ratio of elements in a compound also called simple formulas. Molecular formulas show all atoms of each element in a molecule. Visit BYJU'S to learn more about it.
Several of the problems below include this question and you can go here for a discussion about calculating the molecular formula once you know the empirical formula. Example #1: A 1.50 g sample of hydrocarbon undergoes complete combustion to produce 4.40 g of CO 2 and 2.70 g of H 2 O.

Molecular formulas and empirical formulas are sometimes the same: The molecular formula for water is H 2 O, a 2 to 1 ratio. Since the subscripts will not reduce H 2 O is also water's empirical formula. Molecular formulas and empirical formulas are not always the same: The molecular formula for glucose is C 6 H 12 O 6, not a 1 to 1 ratio.
