1. The problem statement, all variables and given/known data The empirical formula of a compound is C3H2O. If the molar mass of this compound is 192.8, what is its molecular formula? 1. C12H8O4 2. C7H4O 3. C9H6O3 4. C15H10O5 2. Relevant equations 3. The attempt at a solution I'm having trouble with this question, I am not getting a whole number value for mass so I don't know what to do. I did this: 3C->36g , 2H -> 2g , O -> 16 g, TOTAL: 54g Compound: 192.8. 192.8/54 = 3.57. Therefore, I guess it could be a or b as an answer, but I don't know what to do. Can someone help?
