Question

A 4L solution of 1M NaCl is mixed with 3L solution of 1.5M CaCl2 and 3L of 2M solution of AlCl3. What is the final concentration of chloride ions?

Answer 1

First find the total moles of \(Cl^{-}\) that you have in the given mixture. Divide it by total volume.

Formula used here is : of Molarity : \(\textbf{Molarity}= \cfrac{\textbf{Total moles}}{\textbf{Liter(Volume) of Solution }}\)
