Question

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?

Answer 1

Answer: The molarity of the new solution is 0.23 M.

Step-by-step explanation:

Given:
`V_(1)` = 0.30 L,
`M_(1)` = 2.0 M

`V_(2)` = 2.6 L,
`M_(2)` = ?

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

`M_(1)V_(1) = M_(2)V_(2)`

Substitute the values into above formula as follows.

`M_(1)V_(1) = M_(2)V_(2)\\2.0 M * 0.30 L = M_(2) * 2.6 L\\M_(2) = 0.23 M`

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