A chemist wants to make 450. mL of a solution that is 0.500 M in concentration of Zn2+. Her available materials are 1.45 M ZnSO4 and 0.200 M ZnCl2. Unfortunately for the chemist, there is no deionized water available to dilute the solutions. Assuming that the solutions’ volumes are additive, how many mL of each solution are required to make the 450. mL of 0.500 M Zn2+solution? Which of the ions present has the lowest concentration in the final solution?
Volume of 1.45 M ZnSO4
Volume of 0.200 M ZnCl2
Ion with lowest concentration in final solution
