    The molarity of a solution of CaCl2 is calculated as below

    convert mm to g

    1mg = 0.001 g

    what about 33500 mg=? g

    33500 x 0.001 = 33.5 g

    find the moles of CaCl2 = mass/molar mass

    =33.5 g / 111 g/mol = 0.3018 moles

    molarity = moles/volume

    =0.3018/0.352 = 0.857 M
