You have 50 milliliters of a 0.45 M MgBr2 solution and dilute it to a total volume of 300 milliliters. What is the molarity of the resulting solution? Describe in words how you will find the new molarity.

Given :

Initial volume , .

Final volume , .

Initial molarity , .

To Find :

Molarity of  300 ml solution .

Solution :

We know , for constant moles .

Therefore , the molarity of the resulting solution is 0.075 M.

Hence , this is the required solution .
