The molecular mass is twice the formula mass 18088 20 so the simplest formula must be multiplied by 2 to get the molecular formula. To find the molecular formula using this empirical formula we first need to find the number of empirical formula units present in the compound. The two formulae are related by a whole number ratio such that if the empirical formula is multiplied by the ratio it will yield the molecular formula.
Glucose has a molecular formula of C 6 H 12 O 6.
Molar mass of empirical formula unit CH2O 12 gmol 1gmol x 2 16gmol 30 gmol. On the other hand empirical formula shows simpler whole-integer ration of the atoms within a compound. Hence the empirical formula of the compound is CH 2 O. A molecular formula is not the chemical name of the compound but it is defined with no words.
