Answer:

What do you think is the importance of knowing the mass percentages of elements in a compound?

Having information about the percent composition of a compound will allow you to determine the mole:mole ratio of elements present in a compound. ... If you know molecular weight and empirical formula for a covalently bonded compound you can calculate molecular formulas.

How would you know if what you got is the empirical formula or the molecular formula?

Molecular formulas tell you how many atoms of each element are in a compound, and empirical formulas tell you the simplest or most reduced ratio of elements in a compound. If a compound's molecular formula cannot be reduced any more, then the empirical formula is the same as the molecular formula.

Based on the activity, differentiate empirical formula and molecular formula.

Empirical formulas show the simplest whole-number ratio of atoms in a compound, molecular formulas show the number of each type of atom in a molecule, and structural formulas show how the atoms in a molecule are bonded to each other.
