Identify the molecular formulas of each compound in the pairs given. For example, the first pair is C6H12O6 and C2H4O2.
Determine the empirical formula for each compound by finding the simplest whole-number ratio of atoms. To do this, divide the subscripts of each element by their greatest common divisor (GCD).
For C6H12O6, find the GCD of 6, 12, and 6, then divide each subscript by this number to get the empirical formula.
For C2H4O2, find the GCD of 2, 4, and 2, then divide each subscript by this number to get the empirical formula.
Compare the empirical formulas of the two compounds in each pair. The pair with identical empirical formulas has the same simplest ratio of atoms.
