#### Answer:

#### Explanation:

When a solution is diluted, the number of mole of particles in the solution does not change.

The relationship between the number of mole

where,

If we consider that initially the volume and the molarity are:

What would be the final molarity

since the number of mole does not change, we can write:

Here is a video that discusses the solution preparation and dilution:
