An unknown solution has a molarity of 1.30 x 10^-5 M. 3.0 mL of the solution is placed in a test tube with 2.0 mL of water. Then 1.0 mL of bleach with a molarity of 0.712 M is added. How do you calculate the molarity of this dilute solution?

Second of all you are searching the molarity of what compound? If you are looking for the molarity of bleach? It's simple unles the unknown compound contains bleach? If not you do the next: The total volume is 6 mL. You have 1 mL of 0.712 M Divide 0.712 by 6 and you have the molarity of your bleach solution which is 0.119 M. If you have more question, ask away
