Molarity Calculation Worksheet Solutions and Explanations, Exercises of Chemistry

The solutions and explanations for a molarity calculation worksheet. It covers various scenarios where different amounts of solute are dissolved in different volumes of water to create solutions, and explains how to calculate the molarity using the given molar mass and the formula: molarity = moles of solute / liters of solution.

Molarity Worksheet

Find the molarity of the following solutions:

  1. 0.5 moles of sodium chloride is dissolved to make 0.05 liters of solution.
  2. 0.5 grams of sodium chloride is dissolved to make 0.05 liters of solution.
  3. 0.5 grams of sodium chloride is dissolved to make 0.05 mL of solution.
  4. 734 grams of lithium sulfate are dissolved to make 2500 mL of solution.
  1. 6.7 x 10
  • 2 grams of Pb(C 2 H 3 O 2 ) 4 are dissolved to make 3.5 mL of solution.
  1. I have two solutions. In the first solution, 1.0 moles of sodium chloride is dissolved to make 1.0 liters of solution. In the second one, 1.0 moles of sodium chloride is added to 1.0 liters of water. Is the molarity of each solution the same? Explain your answer.

of the water plus the volume of the salt, which will be greater than 1. L. It is for this reason that when you make a solution, you always dissolve the solute in only a little bit of water and then add water to make your final volume.
