Bellwork 2. Which piece of equipment would work best for measuring 24 mL?

Bellwork 2. Which piece of equipment would work best for measuring 24 mL? The graduated cylinder would be most appropriate for measuring 24 mL because it is precise enough to measure volume to the nearest mL. The other equipment pictured is not precise enough.

Bellwork 2. Which piece of equipment would work best for measuring 750 mL?

Bellwork 2. Which piece of equipment would work best for measuring 750 mL? The beaker would be most appropriate for measuring 750 mL. The graduated cylinder is not large enough, and the Erlenmeyer flask is not precise enough to measure to the nearest 50 mL.

Bellwork 3. Which unit of measure is used for equipment D? What is it measuring (mass, volume, weight, length, or area)?

Bellwork 3. Which unit of measure is used for equipment D? What is it measuring (mass, volume, weight, length, or area)? The beaker measures volume in milliliters (mL).
