Practice
7 questions
Define molarity and explain what it represents in the context of solutions.
If you have 5 grams of NaCl (molar mass = 58.44 g/mol) dissolved in 250 mL of water, what is the molarity of the solution?

Quick comprehension check
“If you have 50.0 mL of a 2.0 M solution and dilute it to 250.0 mL, what is the final molarity of the diluted solution? You need to prepare 100.0 mL of a 0.5 M solution using a 4.0 M stock solution. What volume of the stock solution, in mL, is required? A chemist dilutes 20.0 mL of a 3.0 M solution to a final concentration of 0.75 M. What is the final volume of the diluted solution, in mL?”
