Posted by Christian on Tuesday, March 1, 2011 at 12:51pm.

80.0 grams of KBr is mixed with sufficient water to prepare 1865 mL of solution. This solution is then mixed with 46.3 mL of 0.425 M KCl solution. 12 mL of this mixture is subsequently added to 61.0 mL of distilled water. Calculate the molarity of K+ ions in the final mixture? KBr and KCl dissolve in water according to the following processes.

KCl(s)+H2O(l) yields K+(aq)+Cl-(aq)
KBr(s)+H2O(l) yields K+(aq)+Br-(aq)
