Verified step by step guidance
1
Understand that the problem is asking for the laboratory instrument used to measure the mass of a substance.
Recall the function of each listed instrument: a burette measures volume of liquids, a thermometer measures temperature, and a graduated cylinder measures volume as well.
Recognize that mass is a measure of the amount of matter in an object, which requires a device that can quantify weight or mass directly.
Identify that a balance is the instrument designed to measure mass by comparing the object to known masses or by electronic measurement.
Conclude that the balance is the correct instrument for measuring mass in the laboratory.
