We’re being asked to determine what you would **add (solute or solvent) to obtain the following solution**

Recall that **molarity** is given by:

$\overline{){\mathbf{Molarity}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}\frac{\mathbf{moles}\mathbf{}\mathbf{of}\mathbf{}\mathbf{solute}}{\mathbf{Liters}\mathbf{}\mathbf{of}\mathbf{}\mathbf{solution}}}$

Our initial solution contains 8 molecules in a 1.0 L solution. Its concentration is 1 M.

This means 1 mole of solute has 8 molecules.

We will do the following steps to solve the problem:

Step 1: Determine the concentration of the final solution

Step 2: Determine the solute or solvent to be added

**For a, **

**Step 1**: Determine the concentration of the final solution

The circle below represents 1.0 liter of a solution with a solute
concentration of 1 M:

Explain what you would add (the amount of solute or volume of solvent) to the solution so as to obtain a solution represented by each of the figures (a) - (c)?
