  1. Ca(C2H3O2).

    %Ca = [(mass Ca)/(mass calcium acetate)]*100

    %H = [(mass H)/(mass calcium acetate)]*100

    %O = [(mass O)/(mass calcium acetate)]*100

    %C = [(mass C)/(mass calcium acetate)]
    *100

    Use atomic mass for mass of the atoms multiplied by the number of atoms in calcium acetate.
    Use molar mass of calcium acetate for its mass.
