- 6-74 An osmotic semipermeable membrane that allows only water to pass separates two compartments, A and B. Compartment A contains 0.9% NaCI, and compartment B contains 3% glycerol C3H8O3. (a) In which compartment will the level of solution rise? (b) Which compartment (if either) has the higher osmotic pressure?arrow_forward6-18 Suppose you prepare a solution by dissolving glucose in water. Which is the solvent, and which is the solute?arrow_forward6-75 Calculate the osmolarity of each of the following solutions. (a) 0.39 M Na2CO3 (b) 0.62 M AI(NO3)3 (c) 4.2 M LiBr (d) 0.009 M K3PO4arrow_forward
- 6-111 As noted in Section 6-8C, the amount of external pressure that must be applied to a more concentrated solution to stop the passage of solvent molecules across a semipermeable membrane is known as the osmotic pressure The osmotic pressure obeys a law similar in form to the ideal gas law (discussed in Section 5-4), where Substituting for pressure and solving for osmotic pressures gives the following equation: RT MRT, where M is the concentration or molarity of the solution. (a) Determine the osmotic pressure at 25°C of a 0.0020 M sucrose (C12H22O11) solution. (b) Seawater contains 3.4 g of salts for every liter of solution. Assuming the solute consists entirely of NaCl (and complete dissociation of the NaCI salt), calculate the osmotic pressure of seawater at 25°C. (c) The average osmotic pressure of blood is 7.7 atm at 25°C. What concentration of glucose (C6H12O6) will be isotonic with blood? (d) Lysozyme is an enzyme that breaks bacterial cell walls. A solution containing 0.150 g of this enzyme in 210. mL of solution has an osmotic pressure of 0.953 torr at 25°C. What is the molar mass of lysozyme? (e) The osmotic pressure of an aqueous solution of a certain protein was measured in order to determine the protein's molar mass. The solution contained 3.50 mg of protein dissolved in sufficient water to form 5.00 mL of solution. The osmotic pressure of the solution at 25°C was found to be 1.54 torr. Calculate the molar mass of the protein.arrow_forward6-113 List the following aqueous solutions in order of decreasing freezing point: 0.040 M glycerin (C3H8O3) 0.025 M NaBr, and 0.015 M AI(NO3)3 Assume complete dissociation of any salts.arrow_forward6-43 The label on a sparkling cider says it contains 22.0 g glucose (C6H12O6) 190. mg K+ , and 4.00 mg Na+ per serving of 240. mL of cider. Calculate the molarities of these ingredients in the sparkling cider.arrow_forward

Explain what happens in each case.arrow_forward6-67 Calculate the freezing points of solutions made by dissolving 1.00 mole of each of the following ionic solutes in 1000. g of H2O. (a) NaCI (b) MgCI2 (c) (NH4)2CO3 (d) AI(HCO3)3arrow_forward

What is the molarity of sucrose in the jam?arrow_forward6-54 An industrial wastewater contains 3.60 ppb cadmium Cd2+. How many mg of Cd2+ could be recovered from a ton (1016 kg) of this wastewater?arrow_forward6-26 On the basis of polarity and hydrogen bonding, which solute would be the most soluble in benzene C6H6?
