Answer:
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 <em>calibrated to contain a precise volume at a certain temperature. </em>
That means if you want to make a solution with accuracy you must use a <em>250mL volumetric flask</em>.
I hope it hepls!
