This is a set of practice problems for Solutions.
  1. Calculate the molarity of a solution made by dissolving 23.4 grams of sodium sulfate in enough water to form 125 milliliters of solution. Answer
  2. How much 3.0 M sulfuric acid would be required to make 450 milliliters of 0.10 M H2SO4? Answer
  3. How many moles of potassium ions, (K+), are present in 0.25 liters of 0.015 M potassium carbonate? Answer
  4. Write balanced molecular, ionic, and net ionic equations for the precipitation reaction (if any) that occurs when solutions of BaCl2 and Na2SO4 are mixed. Answer
  5. What is the molarity of an NaOH solution if 48.0 milliliters of it are needed to neutralize 35.0 milliliters of 0.144 M H2SO4? Answer
  6. What is the difference between 0.50 mol HCl and 0.50 M HCl? Answer
  7. Pure acetic acid, known as "glacial acetic acid," is a liquid with a density of 1.049 g/ml at 25oC. Calculate the molarity of a solution of acetic acid made by dissolving 10.00 milliliters of glacial acetic acid at 25oC in enough water to make 100.0 milliliters of solution. Answer
  8. An experiment calls for you to use 200 milliliters of 1.0 M HNO3 solution. All you have is a bottle of 6.0 M HNO3 and a tap for distilled water. How much of the concentrated nitric acid would you need to prepare the solution? Answer
  9. By titration, 15.0 milliliters of 0.1008 M NaOH is required to neutralize a 0.2053-gram sample of an organic acid. What is the molar mass of the acid if it contains one acidic hydrogen? An elemental analysis of the substance indicates that it is composed of 5.89% hydrogen, 70.6% carbon, with the remainder being oxygen. What is the molecular formula of the compound? Answer
