To prepare a 1 V/V (volume/volume) solution, you mix equal volumes of the solute and solvent. Here’s how you can do it:

1. Determine the total volume of the solution you need. For instance, if you want to prepare 100 mL of a 1 V/V solution, measure out 50 mL of the solute and 50 mL of the solvent.
2. Accurately measure the required volume of the solute using a graduated cylinder or pipette.
3. Then, use another graduated cylinder to measure the same volume of the solvent.
4. Mix the two volumes together in a clean container. It’s essential to stir well to ensure that the solute is evenly distributed within the solvent.
5. Label your solution with the concentration and date of preparation for future reference.

Keep in mind that the solute and solvent should be miscible (able to mix) for this ratio to work effectively. Also, always wear appropriate safety gear when handling chemicals.
