How do you know when to solve for a empirical formula?
If it tells you to find the empirical formula when percent composition is given or if the mass of each element is given in a specific compound.

What is the empirical formula for a compound that is 7.9 percent Li and 92.1 percent Br?
The atomic mass of lithium is 6.94, while that for bromine is 79.90. 7.9/6.94 = 1.095 and 92.1/79.90 = 1.15. the closest integer ratio between these two number si 1:1, so the empirical formula is LiBr.

Can you determine the molecular formula of a substance from its percent composition?
Not completely. The empirical formula of a substance can be determined from its percent composition, but a determination of molecular weight is needed to decide which multiple of the empirical formula represents the molecular formula.

Explain why the percent composition of certain compounds are not sufficient to determine the compounds molecular formulas?
Because unlike the empirical formula, the molecular formula does not have to be the simplest ratio.If by chance you are given the percent composition of the elements in a substance, you could calculate the empirical formula and then the empirical formula's mass. However, the molecular formula equation is molecular formula= (empirical formula)n, where n is the mass of the molecular formula divided by the mass of the empirical formula. You would, therefore, need to know the mass belonging to the molecular formula, which you are not given.
