The gram molecular weight of the Cacl2 ( or the mass of 1Mole of Cacl2) = gram molecular weight of Ca(or a mass of1 mole of Ca) +2 gram molecular weight of cl (or a mass of 2 moles of Cl ) = 132.90gram+2*35.45 gram = 203.8gm of CaCl2

Therefore 0.1M  of the substance of Cacl2 has the mass of 203.8*0.1 grams of CaCl2 = 20.38 gram of CaCl2
