Problem

How could you prepare a 3.08 m aqueous solution of glycerin, C3H8O3? What is the freezing point of this solution?

Solution
  • Recall that molality can be calculated as:

  • Therefore, if we have 3.08 m of glycerin, this will appear as:

  • We need to calculate for the mass of C3H8Ousing the provided moles and MM. Assuming that we will be using 1 kg of solvent/water
