The empirical formula would be CH3. This is as the empirical formula is determined by dividing the number of moles for each element in the compound by the least number of moles of a constituent element. Based on the ratio provided (2 to 6), carbon has the least number of moles. Hence, 2/2=1 and 6/2=3.
