Which of the following laboratory materials is the best choice to accurately measure the volume of water?

• A. Erlenmeyer flask
• B. Test tube
• C. Graduated cylinder
• D. Beaker

Answer: (C)

Verified step by step guidance

1. Understand that the goal is to accurately measure the volume of water, which requires a piece of laboratory equipment designed for precise volume measurement.
2. Recall the typical uses and accuracy of each option: an Erlenmeyer flask is mainly for mixing and heating liquids, not precise volume measurement; a test tube is used for holding small amounts of liquid but not for measuring volume accurately; a beaker is used for approximate volume measurements and mixing, but it is not very precise.
3. Recognize that a graduated cylinder is specifically designed to measure liquid volumes accurately, with marked graduations that allow for precise readings.
4. Consider the design features of a graduated cylinder, such as narrow diameter and clear volume markings, which reduce the uncertainty in volume measurement compared to other glassware.
5. Conclude that among the given options, the graduated cylinder is the best choice for accurately measuring the volume of water.
