    0.2M means 0.2mol CaCl2/1L solution.

    This question didn't give us a density of the solution so needs an assumption that the solution has equal volume to water.

    xmol/0.5L=0.2M

    x = 0.1

    0.1mol of CaCl2 is needed. Ca=40g/mol, Cl=35.5g/mol.

    CaCl2 0.1mol = (40+35.5*2) * 0.1=11.1g
