Question

What is the molarity of a solution that contains 8 g of `CaCl_2` in 400 mL of water?

Answer 1

`"Concentration"="Moles of solute"/"Volume of solution"`

Explanation:

`"Concentration "=(8.0*cancelg)/(110.98*cancelg*mol^-1)xx1/(0.400*L)` `=` `0.180*mol*L^-1` with respect to calcium chloride.

What is the concentration with respect to chloride ion?
