You are a lab technician and must create 250 ml of a 17% salt-solution.

a. If you have 500 ml of 28% salt-solution, how many milliliters of it should you mix with water in order to create 250 ml of a 17% salt-solution?

b. If you have 400 ml of 40% salt-solution, how many milliliters of it should you mix with water in order to create 250 ml of a 17% salt-solution?

c. If in parts a and b above we use respectively V1 milliliters at salt concentration of C1 and V2 milliliters at salt concentrations of C2 then give a mathematical proof to show that C1/V1=C2/V2.

d. Use the above formula along with the results in part a to determine the number of milligrams of 35% salt-solution would be needed to mix with water to create 250 ml of 17% solution.

e. What is the domain of Ci in the formula in part c?
