Isotonic saline solution, which has the same osmotic pressure as blood, can be prepared by dissolving 0.923 g of NaCl in enough water to produce 100. mL of solution. What is the osmotic pressure of this solution at 25C? Express your answer to three significant figures and include the appropriate units. View Available Hint(s) HA ? IPi = 7.716 atm Your answer contains correct dimensions of pressure, but you need to use the appropriate Sl unit or prefix for the unit. No credit lost. Try again. Osmosis is the process responsible for carrying nutrients and water from groundwater supplies to the upper parts of trees. The osmotic pressures required for this process can be as high as 19.6 bar. What would the molar concentration of the tree sap have to be to achieve this pressure on a day when the temperature is 35 C ?
