An unknown compound has a percent composition of 52.10% potassium, 15.8% carbon, and 32.1% oxygen. The molar mass of the compound is 150.22 g/mol. What is the empirical formula and the molecular formula of this compound?
The empirical formula is
As is typical with these questions, we assume
Now if we divide thru by the lowest molar quantity, we get
Thus, solving for
This corresponds to no reasonable formula I know;
