Chapter 6, Problem 34RA

Suppose a semipermeable membrane separates two solutions. One solution has 0.72  g glucose to 1.0  L of water; the other has 0.117  g NaCl to 1.0  L of water. Given that glucose has a molecular weight of 180 and NaCl has a molecular weight of 58.5, perform the following calculations.

Calculate the molality and osmolality of each solution (see fig. 6.10).

Students have asked these similar questions
Solution A: 200 mM glucose; solution B: (100 mM NaCl + 50 mM KCl). Which of these two solutionswill have the highest osmotic pressure and why?
yeasts are able to produce high internal concentrations of glycerol to counteract the osmotic pressure of the surrounding media. suppose that a sample of yeast cells were placed in a 4% sodium chloride solution by weight.  The density of solution is at 25 C = 1.02 g/ml, Molecular weight of solute = 58.44 g/mol, i of glycerol = 1 and R=0.08205 L-atm/mol-K  What is the weight of solute in grams What is the moles of solute What is the volume of the solution in liters What is the molarity of the solution What is the value of the temperature to be used to solved for the osmotic pressure of the solution  What is the osmotic pressure of solution
A membrane consists of 50% protein by weight and 50% phosphoglycerides by weight. The average molecular weight of the lipids is 800 Da, and the average molecular weight of the proteins is 50,000 Da. Calculate the molar ratio of lipid to protein.
