You can divide all three elements by 6 to give: CH2O. So, The formula mass of CH is (12+1) = 13 amu or 13 g/mol. (b) Calculate the molarity of a solution… *Response times vary by subject and question complexity. The empirical formula weight of CH 2 O = 12.01 + 2 × 1.008 + 16.00 = 30. I've already tried to solved this I tried C6H12O6 and C3H6O3 both wrong. 1. It is equal to 6 x 30 g/ mol. They are different for glucose. Median response time is 34 minutes and may be longer for new subjects. 6. Relevance. The empirical formula is when you can not simplify the formula any further. Find the molecular formula of glucose. What is the empirical formula of glucose, C6H12O6? Join now. Empirical formula mass or formula mass is equal to the sum of atomic masses of all the atoms present in the empirical formula. So the numbers we have in this formula are 6,12, and 6. Quick Revision/Atomic Structure/P.4 Example A compound X contains 80 % carbon and 20% hydrogen by mass.
