2. In an experiment it was found that 8.25 g of potassium (K) combines with 6.75 g of oxygen (O) to produce a compound. What is its empirical formula of the compound?
K (8.25/39)O(6.75/16)=K(.21)O(.42) this is the mole ratio or .21 mole K to .42 mole O. This would then be .21/.21 = 1 .42/.21 =2 or KO2. Does not make sense. Should be K2O
