Question

select the most appropriate tool for each measurement.
exactly 200.00 ml salt solution: volumetric flask
a 0.02 - ml acid solution: 1 - ml pipette
approximately 400 ml water: beaker
exactly 77.5 ml methanol:

Explanation:

Step1: Understand the tools' functions

A volumetric flask is for precise volume (e.g., 200.00 mL). A pipette (e.g., 1 - mL) for small, precise volumes. A beaker for approximate measurements. A graduated cylinder for moderately precise volumes (e.g., 77.5 mL).

Step2: Select the tool for 77.5 mL methanol

Since 77.5 mL is a moderately precise measurement, a graduated cylinder is appropriate. A beaker is too approximate, and a volumetric flask or pipette is for different volume ranges.

Answer:

graduated cylinder
