Two aqueous solutions are prepared in which one contains 0.275 moles of the nonvolatile solut glucose (C6H12O6) dissolved in 2500.00 g of water and the other solution contains 0.275 moles of the nonvolatile solute CaCl2 dissolved in 2500.00 g of water. Describe how each of the colligative properties listed below would be affected for each of these solutions (for each property, describe if there is a decrease or an increase then identify which of the solutions (C6H12O6 or CaCl2) would cause the greater effect). In addition, choose only 1 of the colligative properties (choose either the melting point or boiling point) and show how to determine (and then calculate) the magnitude of the change and resulting value for either the melting point or boiling point for each of these solutions (follow worked example 9.15 and 9.16 in 4. your text).
