A solution is prepared by dissolving 23.7 g of CaCl2 in 375 g of water. The density of the resulting
solution is 1.05 g/mL. The concentration of Cl- in this solution is __________ M.

can someone help me? how do i get to M?

  • Chemistry -

    23.7/molar mass CaCl2 = moles CaCl2
    moles Cl^- = 2 times that.
    Convert 3675 g water to liters using the density. Then M = mols/L.
