When 2.5000 g of an oxide of mercury, (hg soy) is decomposed into the elements by heating, 2.405 g of mercury are produced. calculate the empirical formula?
For Hg : 2405 g mol / 200.59 g = 0.0012 mol For O: ( 2.5000 - 2.405 ) g mol / 15.999 g = 0.006 mol 0.012 : 0.006 = 2 Hg 0.006 : 0.006 = 1 O Answer: The empirical formula is Hg 2 O.
