# What is the concentration of 15.6*g of "calcium chloride" dissolved in a volume of 250*mL?

$\text{Concentration"="Moles of solute"/"Volume of solution}$
"Concentration with respect to calcium chloride"=(15.6*g)/(110.98*g*mol^-1)xx1/((0.250*L) $=$ ??*mol*L^-1.
What is the concentration with respect to $C {a}^{2 +}$, to $C {l}^{-}$?
