A chemistry student attempted to make a 0.2000 M solution of NaCl using a 100.0 mL volumetric flask.The Student added exactly 100.0 mL of water to the flask, then added 0.02000 mol of NaCl, and found that the total volume in the flask was above the 100.0 mL mark.What was the concentration of the solution?

Question

Quizplus · Accepted Answer

Adding solid NaCl to water already measured to 100.0 mL increases the total volume, meaning the concentration is less than 0.2000 M because the solute is dissolved in a volume greater than 100.0 mL.
