1) A student obtains 0.30 liters of 2.0 M silver nitrate solution. She dilutes the solution until it has a volume of 2.6 liters. What is the molarity of
the new solution?

The molarity of the new solution is 0.23 M.

Explanation:

Given: = 0.30 L,     = 2.0 M

= 2.6 L,               = ?

Formula used to calculate the molarity of new solution is as follows.

Substitute the values into above formula as follows.

Thus, we can conclude that the molarity of the new solution is 0.23 M.

a is the correct answer
