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.
