In order to prepare the described solution in the laboratory, two quantities must be measured accurately. One of these quantities is the volume of the solution. What other quantity must be measured in the laboratory to prepare this solution?

The other quantity should be Mass of the compound.

Explanation:

The solution is a kind of mixture in which solute particles are uniformly distributed in the solvent and thus homogenous in nature and is formed by mixing of solvent and solute. Generally solvents are present in the form of the liquid and the solute is present in the form of solid or liquid. So during the preparation of the solutions, the volume of the solvent and mass of the solute is required. To calculate the number of moles, the mass of the solute is must known. So mass is the best other quantity that should be measured during the solution preparation process.
