Which of the following sets of empirical formula molar mass and molecular formula is correct?

To determine the correct set of empirical formula molar mass and molecular formula, you need to compare the empirical formula's mass with the molecular formula's mass. The molecular formula is a whole-number multiple of the empirical formula. Without specific options provided, I cannot identify the correct set, but generally, you would calculate the molar masses and ensure the molecular formula is a multiple of the empirical formula. Please provide the specific sets for a more precise answer.
