Thermometer
B
Graduated cylinder
C
Buret
D
Balance
Verified step by step guidance1
Understand the purpose of each laboratory instrument listed: a thermometer measures temperature, a graduated cylinder measures volume, and a buret is used to deliver precise volumes of liquid during titrations.
Recall that mass is a measure of the amount of matter in an object or substance, and it is typically measured in units such as grams or kilograms.
Identify the instrument designed specifically to measure mass, which is the balance. Balances can be mechanical or electronic and provide the mass of an object by comparing it to known masses or through electronic sensors.
Recognize that the balance is the correct choice because it directly measures mass, unlike the other instruments which measure temperature or volume.
Summarize that when you need to find the mass of an object or substance in the laboratory, you should use a balance.
