    830 mL. A 2.3 mol/L solution of CaCl2 has a volume of 830 mL

    I am guessing that the concentration of your solution is 2.3 mol/L.

    a) Moles of CaCl2

    MM of CaCl2 = 110.98 g/mol

    Moles of CaCl2 = 212 g CaCl2 x (1 mol CaCl2/110.98 g CaCl2)

    = 1.910 mol CaCl2

    b) Volume of solution

    V = 1.910 mol CaCl2 x (1 L solution/2.3 mol CaCl2) = 0.83 L solution

    = 830 mL solution
