A student needs to prepare 250 mL of a 0.400 M aqueous solution of sucrose, C 12 H 22 O 11 ( aq ) , which is used frequently in biological experiments. A 250 m L beaker. A A 250 m L erlenmeyer flask. B A 250 m L volumetric flask. C Which type of glassware should be used to make this solution (assuming that the accuracy of the concentration is important)

250mL volumetric flask

Explanation:

A beaker is a cylindrical glass or plastic vessel used for holding liquids. Its principal use is not measuring volumes with accuracy

An erlenmeyer flask is used to mixing or stirring solutions, is not used to measure volumes.

A volumetric flask is a glass instrument used in lab that is calibrated to contain a precise volume at a certain temperature.

That means if you want to make a solution with accuracy you must use a 250mL volumetric flask.

I hope it hepls!
