If a copper acetate hydrate, cux(c2h3o2)y zh2o compound is found to contain 31.82% copper, 59.14% acetate, and the remainder is water. what is the empirical formula of this compound ?

In empirical formulas, we find the minimum ratio to which the components of the compound are combined in.
Cux(C2H3O2)y zH2O 
first we need to write the percentages as masses and assume that in 100 g of the compound these are the masses of each compound its composed of
                  Cu                           C₂H₃O₂          H₂O
                31.82 g                      59.14 g        9.04 g
 molar mass
                 63.5 g/mol                 59 g/mol        18 g/mol
            31.82/63.5                    59.14/59        9.04/18
            = 0.5                             = 1.002          - 0.5
divide by the smallest number 
               0.5/0.5 = 1                   1.0/0.5 =2      0.5/0.5 = 1

Therefore x = 1
                y = 2
                z = 1
