To solve this problem, you need to start by find the molar mass of the empirical formula, CH. Now you need to divide the molar mass of the compound by the molar mass of the empirical formula. That will tell you which multiple is correct. So the molecular formula is the sixth multiple of the empirical formula. Simply multiply the subscripts of the empirical formula (CH) by 6, and you have your answer. |
