(C) $1$. Calculate the moles of $CaCl_2$: $\text{moles} = \frac{222 \times 10^{-3} \ g}{111 \ g/mol} = 2 \times 10^{-3} \ mol$.$2$. Calculate the final molarity of $CaCl_2$ after dilution to $100 \ mL$ $(0.1 \ L)$: $M = \frac{2 \times 10^{-3} \ mol}{0.1 \ L} = 0.02 \ M$.$3$. Dissociation of $CaCl_2$: $CaCl_2 \rightarrow Ca^{2+} + 2Cl^-$.$4$. Concentration of $Cl^-$ ions: $[Cl^-] = 2 \times [CaCl_2] = 2 \times 0.02 \ M = 0.04 \ mol/L$.
