Which laboratory tool is most appropriate for accurately measuring the volume of a sample of water?
A

B
Graduated cylinder
C
Erlenmeyer flask
D
Bunsen burner
Verified step by step guidance1
Understand that the goal is to measure the volume of a liquid sample accurately.
Recall that a beaker and an Erlenmeyer flask are primarily used for mixing, stirring, and rough volume estimates, but they are not very precise for volume measurements.
Recognize that a Bunsen burner is a heat source and not a measuring tool, so it is not suitable for measuring volume.
Identify that a graduated cylinder is specifically designed with marked graduations to measure liquid volumes accurately and precisely.
Conclude that among the given options, the graduated cylinder is the most appropriate laboratory tool for accurately measuring the volume of a water sample.
