mol-1 to get 2.00. So, you then multiply 2 by each "coefficient" of the elements, so C3H4O3 becomes C6H8O6. C3H4O3 is the empirical formula and C6H8O6 is the molecular formula for Vitamin C. Hope this helped!

Explanation: If I asked how many atoms there were in a dozen formula units of BaCl2 , I think you would quickly answer 3 dozen: 12 barium atoms, and 24 chlorine atoms. The question specified molar quantities, and the mole is just another number, admittedly a very large number, i.e. NA = 6.022×1023 mol−1 .
