Question

You have 100 mL of a 6 M solution of NaCI and you need to dilute it to 400 mL. What is the molarity of the new solution?

Answer 1

Answer: 1.5 M

Step-by-step explanation:

In order to find the molarity of the new solution, we need to use the formula M1V1 = M2V2, where M1 is the initial molarity, V1 is the initial volume, M2 is the final molarity, and V2 is the final volume.

Given that the initial volume is 100 mL and the initial molarity is 6 M, we can plug in the values and solve for M2:

6 M x 100 mL = M2 x 400 mL

M2 = (6 M x 100 mL) / 400 mL

M2 = 1.5 M

So the new solution will have a molarity of 1.5 M.
