Question

select the most appropriate tool for each measurement.
exactly 200.00 ml salt solution:
beaker
volumetric flask
approximately 400 ml water:
exactly 77.5 ml methanol:

Explanation:

• A volumetric flask is designed to measure a single, precise volume (in this case, 200.00 mL).
• A beaker is used for approximate volume measurements (like approximately 400 mL).
• A graduated cylinder can measure an exact volume (such as 77.5 mL) with reasonable precision.

Answer:

Exactly 200.00 mL salt solution: volumetric flask
Approximately 400 mL water: beaker
Exactly 77.5 mL methanol: graduated cylinder
