Question:

Describe how to prepare 250 mL of 0.1500 M NaCl with a 250 mL volumetric flask.

Volumetric Flask:

A volumetric flask is a very specific pear-shaped type of glassware used for making solutions with greater accuracy of total volume. When making a solution, the solute is added and the solvent fills up the flask to a line. Volumetric flasks come in a range of sizes including 1 mL, 10 mL, 100 mL, 250 mL, and 1.0 L.
