What volume (in mL) of water would have to be added to 150.0 mL of 0.450 M potassium chloride, KCl, to give a solution with a concentration of 0.100 M?

Product of concentration*volume is constant, because number of moles of KCl is the same.
The new volume of solution will be 150.0 mL * 0.450 M / 0.100 M = 675.0 mL.
Volume of water to be added is 675.0 - 150.0 = 525.0 mL.
