The osmotic pressure of human blood is 7.60 atm. What mass of glucose, C6H12O6, is required to make a 2.00 L aqueous solution for intravenous feeding if the solution must have the same osmotic pressure as blood at body temperature, 37 degrees C? Show all work.
1) At physiological temperature (37OC) the osmotic pressure of blood is 7.65 atm. What concentration (% W/V) of potassium chloride (KCl, MW = 74.5) solution has the same osmotic pressure of blood? Assume the specific gravity of the solution is 1. 2)An ophthalmic (eye drop) formulation contains 100 mEq of sodium chloride (molecular weight = 58.5 g/mole). Calculate the amount (in grams) of sodium chloride needed for the formulation. 3)Methanol (CH3OH, MW = 32) is a nonelectrolyte. What is the...
What is the osmotic pressure (in atm) of a 1.36M aqueous solution of urea [(NH2)2CO] at 22.0 degree celsius.?
8. Estimate the melting point and osmotic pressure of a 2.0-L aqueous solution that contains 0.18 mol of NaCl and 0.30 mol of MgCl2 at 25°C. (solution density=1.02 g/cm').
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-g of protein dissolved in sufficient water to form 5.00-L of solution. The osmotic pressure of the solution at 25oC was found to be 1.54-mmHg. (Hint: Remember to convert mmHg to atm) Calculate the molar mass of the protein.

1.) A 0.046 M aqueous solution of FeCl, has an osmotic pressure of 4.09 atm at 28°C. a. Calculate the percentage difference of the van't Hoff factor from the ideal value. b. What should be the concentration of this aqueous solution if this is in ideal condition?
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.
A sealed container with a volume of 2.00 L contains 30.0 atm of pure O2 and 1.35 g of methanol (CH3OH, 32.05 g/mol) at 25 °C. The combustion finishes, and the container is cooled back to 25 °C. What is the final partial pressure of CO2? What is the final total pressure? (20 pts) please give a detailed explanation
A gas with a pressure of 36 atm and a volume of 22.4 L is held at 10.0 °C. What will the pressure (in atmospheres) be if the volume increases to 30.0 L and the temperature increases to 25.0 °C? • Report your answer to two significant figures Provide your answer below:
