Two compounds that contain Cu and Cl have the following masses:
Cpd A: 32.10 g Cu and 17.90 g Cl
Cpd B: 23.64 g Cu and 26.37 g Cl
Are the compounds the same? If not, what is the lowest whole-number mass ratio of Cu that combines with a given mass of Cl?

  1. Cu/Cl =
    32.10/17.90 = 1.79
    23.64/26.37 = .896

    so no way the same compound

    well .896/1 = 896/1000 = 448/500 = 224/250 = 112/125
