Calculate the osmotic pressure at 25°C across a semipermeable membrane separating seawater (1.14 M total particles) from a 0.547 Msolution of aqueous NaCl.
Calculate the osmotic pressure at 25°C across a semipermeable membrane separating seawater (1.14 M total particles)...
Two aqueous solutions, A and B, are separated by a semipermeable membrane. The osmotic pressure of solution A immediately begins to decrease. Which of the following statements is true? Solvent molecules are moving from solution B into solution A. The initial osmotic pressure of solution B is greater than that of solution A. The solvent molecules are moving from the solution of higher osmotic pressure to that of lower osmotic pressure. Both B and C are true statements.
Calculate the osmotic pressure of a 0.0515 M NaCl solution at 25°C. (The van't Hoff factor for NaCl is 1.90)
Problem 5.76. Seawater has a salinity of 3.5%, meaning that if you boil away a kilogram of seawater, when you're finished you'll have 35 g of solids (mostly NaCl) left in the pot. When dissolved, sodium chloride dissociates into separate Na+ and clº ions. (a) Calculate the osmotic pressure difference between seawater and fresh water. Assume for simplicity that all the dissolved salts in seawater are NaCl. (b) If you apply a pressure difference greater than the osmotic pressure to...
Calculate the osmotic pressure of a 0.0539 M NaCl solution at 37.00°C.
6.4 After equilibration the Donnan potential across a membrane separating solution of a negatively charged polyelectrolyte and a solution of sodium chloride is found to be 45 mV (with the polyelectrolyte solution at the lower potential). Calculate the ratio of sodium ion concentrations in the two solutions. (Ignore any a Osmotic movement.) [c/c = 0.173.]
What is the osmotic pressure of 0.250 M aqueous urea (CON2H4) at 25 °C. R = 0.08206 L atm/mol K and R = 8.3145 J/K mol)
Determine the osmotic pressure at 25 °C of an aqueous solution that is 0.028 M NaNO3. p = i M R T (R = 0.08206 atm L/mol K) For some reason the answer is 1.37 atm, but I am getting .685 atm.
Please explain it with steps, Thank you! 5 A cell s a semipermeable membrane through which water may pass. If a cell, having a salinity (salt content) of 1.5% w/v NaCl, is placed in a solution made of normal physiological saline (0.9% w/vNaCl) which way will the water flow? Explain your answer. (Diagrams are OK also, but need to have words explaining it.) Flow of water Bag is a sem permeable Solution in bag "cell" Solution outside of bag (the...
1.a)The average osmotic pressure of sea water is 30 atm (atmospheres). Calculate the concentration of urea (CH4ON2) at 25 ° C that exerts the same pressure as seawater. R = 0.082 atm L/ mol K 1.b) There is a 1M solution of CH3COOH (acetic acid) in a total volume of 450 mL. What is the molality (m) of the solution? (ρ solution = 1.15 g / mL).
Calculate the osmotic pressure of a 0.0995 M iron (III) nitrate solution at 25°C, in units of atm. What concentration of glucose would be needed to make a solution that is isotonic with the iron (III) nitrate solution?
