A. An empirical formula represent a molecule. B. an empirical formula gives the smallest whole number ratio of each type of atom in a MOLECULE. C. The molecular formula can be the same as the empirical formula in some situations. D. An empirical formula must be multiplied by an integer to obtain the molecular formula.
The empirical formula of a chemical compound is a representation of the simplest whole number ratio between the elements comprising the compound. The molecular formula is the representation of the actual whole number ratio between the elements of the compound.he empirical formula is CH 2 O. Step 4: Find the molecular weight of the empirical formula. We can use the empirical formula to find the molecular formula using the molecular weight of the compound and the molecular weight of the empirical formula. The empirical formula is CH 2 O. The molecular weight is.
