Question

If a student needed to obtain 8.0 mL of a liquid for an experiment, the appropriate piece of laboratory equipment to use would be:

A. 50 mL beaker
B. 1.0 mL pipet
C. 50 mL flask
D. 10.0 mL graduated cylinder

Answer 1

The correct piece of laboratory equipment for measuring 8.0 mL of liquid for an experiment would be a 10.0 mL graduated cylinder, as it allows for precise measurements suitable for the required volume.

Step-by-step explanation:

If a student needed to obtain 8.0 mL of a liquid for an experiment, the appropriate piece of laboratory equipment to use would be the 10.0 mL graduated cylinder. A graduated cylinder is specifically designed to measure volumes of liquids accurately. Considering the options given, a 50 mL beaker and 50 mL flask are not suitable for measuring such a small volume as they are typically used for larger volumes and provide less precision in measurement. A 1.0 mL pipet does not have the capacity to measure 8.0 mL in a single measure. Therefore, using a 10.0 mL graduated cylinder ensures precise measurement, as it typically allows users to measure and read volumes to the nearest 0.1 mL and can easily measure out the required 8.0 mL.
