C
Buret
D
Graduated cylinder
Verified step by step guidance1
Understand the quantity to be measured: the diameter of a soda can is a length measurement, specifically the distance across the circular cross-section of the can.
Review the purpose of each measuring tool: a thermometer measures temperature, a buret measures volume of liquids with high precision, and a graduated cylinder measures volume but with less precision than a buret.
Recognize that length measurements, especially diameters, require tools designed for precise linear measurements, such as rulers, micrometers, or vernier calipers.
Identify that a vernier caliper is specifically designed to measure lengths and diameters with high accuracy, often to the nearest 0.01 mm or better, making it ideal for measuring the diameter of a soda can.
Conclude that among the given options, the vernier caliper is the appropriate tool to accurately measure the diameter of a soda can in a chemistry laboratory.
