What is a common tool used to measure mass?

• A. Triple beam scale
• B. Graduated cylinder
• C. Pipet
• D. Beaker

Answer: (A)

Measuring mass is about determining how much matter an object contains by comparing it to known weights. A triple beam scale is a common instrument for this purpose because you slide riders along three beams (hundreds, tens, and grams) until the balance is achieved, and the reading gives the mass in grams. It directly reports the amount of matter present.

The other tools are designed for volume. A graduated cylinder marks milliliters to estimate how much space a liquid occupies; a pipet transfers a precise volume; a beaker is a container used for holding liquids and rough volume measurement, not for precise mass. So the triple beam scale is the best choice when the goal is to measure mass.
