PLEASE HELP ME which of these could be a possible molar mass of a compound with the empirical formula CH3?

15.03 g/mol or any multiple of this, since this is the empirical formula

Explanation:

To find molar mass, look to the periodic table. C is carbon, which has a molar mass of 12.01 g/mol. H is hydrogen, which has a molar mass of 1.008 g/mol. You have one carbon and three hydrogens in this empirical formula, so 12.01 + 3(1.008) = 15.034 g/mol.The empirical formula is the lowest whole number ratio for the elements in a compound. Therefore the answer would be 15.03 g/mol or any multiple of this, since this is the amount for the empirical formula.
