Chapt. 8 Sec. 7 The steps for determining the Empirical Formula of a compound...-obtain the mass of each element present (in grams) -determine the number of moles of each type of atom present -divide the number of moles of each element by the smallest number of moles to convert the smallest number to 1.(If all obtained are integers these are the subscripts in the formula)(If not continue on to the next step) -multiply the numbers you derived in the last step by the smallest integer that will convert all of them to whole numbers, this set of numbers represents the subscripts in empirical formula
