Which has the higher concentration of Cl- ion?

  • Answer:

    Molarity is moles/liters solution, so a 0.10 M solution is 1 mole in 1 L. The 0.15 M solution is 1.5 moles in 1L. In this case, the CaCl2 solution has twice as much Cl, because Ca & Cl are 1:2 (CaCl2), whereas in KCl, they are 1:1. So you have 2 moles of Cl in CaCl2, and 1.5 moles in KCl.
