Molarity Practice Problems 1. Calculate the molarity of a solution prepared by dissolving 1.50 g KMnO4 in 250.00 mL of solution. 2. The stock room attendant at CLC has a 1 pound jar (454 g) of CuSO45 H20. What volume of 2.50 M solution can she make using the contents of the jar? 3. A student would like to make a 0.200 M solution by adding water to 15.0g of Pb(NO3)2. What should be the final volume (in mL)? 4. What volume of 3.20 M NazSOs is needed to obtain 52.4 g of sodium? 5. 45.00 mL of 10.0 M ammonia is diluted to 500.00 mL. What is the concentration of the resulting solution? 6. How would I prepare 1.25 L of 2.50 M H2S04 starting from the concentrated (18.4 M) solution? You must provide directions for making the solution as well as a numerical answer to this problem.
