...solution.? A solution is prepared by dissolving 0.60 g of nicotine in water to make 12 mL of solution. The osmotic pressure of the solution is 7.55 atm at 25 degrees celsius. What is the molecular weight of the unknown solute? The freezing point of ethanol is -114.6 degrees celsius. The molal freezing point depression constant for ethanol is 2.00 degrees celsius/m. What is the freezing point of a solution prepared by dissolving 7.00 g of glycerin in 201 g of ethanol? Will the molal freezing point depression constant for ethanol be less than, equal to or greater than if 10 g of glycerin was added to 201.0 g of ethanol? Explain Briefly.
