Question

Hi :) I am stuck on these questions on my homework

8)If 200. mL of water is added to 300. mL of an aqueous

solution that is 0.533 M in potassium sulfate, what is the concentration of potassium ions in the final solution?


9)What is the molarity (M) of chloride ions in a solution prepared by mixing 114 ml of 0.27 M calcium chloride with 318 ml of 0.407 M aluminum chloride?


10)How many milligrams of MgI2 must be added to 288.6 mL of 0.09 M KI to produce a solution with [I−] = 0.1000 M? Assume that the addition of MgI2 is a negligible change in volume.


11)If volumes are additive and 270 mL of 0.17 M potassium bromide is mixed with 403 mL of a potassium dichromate solution to give a new solution in which [K+] is 0.679 M, what is the concentration of the potassium dichromate used to make the new solution?

Thank you for all the help! I have been stuck on these problems for about an hour :(
