Answer :

Final answer:

To prepare a 2 M solution of potassium nitrate (KNO3), measure the mass of the solute and the volume of the solvent.


Explanation:

The correct quantities that must be measured to prepare a 2 M solution of potassium nitrate (KNO3) are the mass of the solute and the volume of the solvent.

For example, to make a 2 M solution of KNO3, you would need to measure a specific amount of KNO3 (mass of the solute) and dissolve it in a certain volume of water (volume of the solvent) to achieve the desired concentration.
