Finding the Empirical Formula of a compound
... Since the data collected for these questions are very accurate, then fractional mole ratios can be changed to whole numbers by multiplying by the appropriate whole number. e.g. 2.5 x 2 = 5.0 2.25 x 4 = 9.0 2.2 x 5= 11.0 2.33 x 3= 7.0 Note: All values in the empirical formula must be multiplied by th ...
