28) 28) What is the osmotic pressure of a 0.25 M solution of sucrose at 37°C?...
Calculate the osmotic pressure of a 0.204 M aqueous solution of sucrose, C12H22O11, at 37
The osmotic pressure of blood is 7.65 atm at 37 C. How much glucose should be used per L for an intravenous injection that is to have the same osmotic pressure as blood.(R = 8.314 (L-atm/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.
How many grams of sucrose (C_12 H_22 O_11, 342.3 g/mol) would be needed to make 2.5 L of a solution with an osmotic pressure of 14 atm at 25 degree C? (R = 0.0821 L middot atm/K middot mol) A) 0.57 g B) 6.8 g C) 2.0 times 10^2 g D) 4.9 times 10^2 g E) 5.8 times 10^3 g
Figure 4: Osmotic Pressure Tosm = CRT C = the total solute concentration in moles/liter R = the gas constant [0.082 (liter x atm)/(©K x mole)] T = the temperature in Kelvin (K = 273 + °C). The osmotic pressure of a 20% NaCl solution is _the osmotic pressure of a 20% sucrose solution. Refer to Figure 4. (NaCl = 58g/mol; sucrose = 342g/mol) higher than lower than equal to
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)
I’m just missing these two questions ? Help please P24. What is the osmotic pressure π), in atm, at 25 °C of an aqueous solution containing 2.75 grams of beryllium fluoride, BeF2, dissolved in 500 mL of water? BeF2 is an electrolyte compound. [Hint: van't Hoff Factor] & (R 0.0821 L atm/mol K) 2.61 atm b) 3.05 atm 7.15 atm 8.59 atm
Question 20 0/5 pts The osmotic pressure of blood is 7.65 atm at 37°C. If blood were considered a solution of NaCl, what is the molar concentration of NaCl in blood? Assume an ideal van't Hoff factor Where: n = iMRT R is the ideal gas law constant (0.08205 bar mol K and T is the absolute temperature 23.2
please show the work for solving this question 16. What is the osmotic pressure of a 1.50 M solution of sucrose at 21 °c? Take the Van't Hoff factor to be equal to 1. Give your answer in the SI system of units. A. 36.7 atm B. 37.1 atm C. 36.9 x 10-5 atm D. 36.7 Pa E. 36.7 x 105 Pa
The nonvolatile, nonelectrolyte sucrose, C12H22011 (342.30 g/mol), is soluble in water H20. Calculate the osmotic pressure generated when 12.4 grams of sucrose are dissolved in 201 ml of a water solution at 298 K. The molarity of the solution is M. The osmotic pressure of the solution is atmospheres.
