Question

compare the mass of the solution contained in the volumetric flask to the mass of the solution delivered by the volumetric flask. account for differences. which of the two masses, contained or delivered, should you have used in the determination of the density of the solution? why?

Answer 1

The mass of the solution contained in the volumetric flask should be used in the determination of the density of the solution.

Step-by-step explanation:

In order to determine the density of a solution, you need to consider the mass of the solution. The mass of the solution contained in the volumetric flask should be used in the determination of the density, not the mass of the solution delivered by the volumetric flask. The reason for this is that the mass of the solution contained in the flask includes the mass of the solute and the mass of the solvent, while the mass of the solution delivered only includes the mass of the solute. By using the mass of the solution contained in the flask, you are taking into account the complete mass of the solution.
