Suppose you needed to measure exactly 15.0 mL of water for an

experiment. Which graduated cylinder would be the best one to use, and why?

A 50-mL volumetric cylinder with 0.1-mL accuracy scale should be used for this purpose since three significant figures of accuracy are required.

Hello,

A 50-mL volumetric cylinder with 0.1-mL accuracy scale should be used for this purpose since three significant figures of accuracy are required.

Best regards.

A test tube would be used.

Explanation:

The test tube is a laboratory instrument which is a cylinder made of graduated glass used to measure small volumes of liquids (from 5 mL to 2 L). For the measurement of the volume of the liquid, the most appropriate type of specimen must be selected, in this case a 15 mL one. The specimen is closed at the bottom and has a base for support.
