Which three pieces of equipment provide a measurement of volume in mL? Select all three correct options.

A. Beaker
B. Erlenmeyer Flask
C. Graduated Cylinder
D. Weighing Balance
E. Test Tubes
F. Scoopulas
G. Weigh Boat
H. Tongs

Answer :

Final answer:

The three pieces of equipment that provide a measurement of volume in mL are the graduated cylinder, beaker, and Erlenmeyer flask. The graduated cylinder is the most accurate tool for measuring liquid volumes, while the beaker and Erlenmeyer flask are used for more approximate measurements. Other listed items do not measure volume.


Explanation:

Identifying Equipment for Measuring Volume

In a chemistry lab, several pieces of equipment are commonly used to measure volume in milliliters (mL). Of the options provided, the three pieces of equipment that are specifically designed for measuring volume are:

  1. Graduated Cylinder: This is the most accurate piece of equipment for measuring liquid volumes. It has precise markings for measuring various volumes.
  2. Beaker: Although beakers are often used to hold and mix liquids, they do have volume markings and can be used for approximate measurements.
  3. Erlenmeyer Flask: Similar to beakers, Erlenmeyer flasks have volume markings. They are mainly used for mixing solutions but can also serve as a rough measure of volume.

Other items listed, like the weighing balance, test tubes, scoopulas, weigh boats, and tongs, do not measure volume. The graduated cylinder is the most reliable for precise measurements, while the beaker and Erlenmeyer flask are useful for less precise volume estimations.
