Understand the difference between empirical and molecular formulas: the empirical formula is the simplest whole-number ratio of atoms in a compound, while the molecular formula shows the actual number of atoms of each element in a molecule.
For each given compound, determine the ratio of atoms by dividing the subscripts by their greatest common divisor (GCD) to find the empirical formula.
Compare the empirical formula to the molecular formula for each compound. If they are the same, then that compound has identical empirical and molecular formulas.
For example, for a compound with formula \(C_6H_{12}O_6\), divide each subscript by 6 (the GCD) to get the empirical formula \(C_1H_2O_1\) or \(CH_2O\).
Repeat this process for the other compounds and identify which one’s empirical formula matches its molecular formula exactly.
