Verified step by step guidance1
Understand the purpose of each laboratory tool: a graduated cylinder measures volume, a thermometer measures temperature, a buret dispenses precise volumes of liquid, and a balance measures mass.
Recall that mass is the amount of matter in an object, which is different from volume or temperature.
Identify that the tool designed specifically to measure mass is the balance, as it provides a direct measurement of how much matter is present.
Recognize that the other tools (graduated cylinder, thermometer, buret) are not suitable for measuring mass because they measure different physical properties.
Conclude that the balance is the most appropriate laboratory tool for measuring the mass of a substance.
