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.

Does the compounds C2H2 and C6H6 have the same percent composition by mass?
It does not necessarily mean that. For example glucose (C6H12O6) and formaldehyde (CH2O) have the same percentages of elements by mass, but are two very difference compounds.
