The osmotic pressure of a solution is calculated using the formula =MRT What is the osmotic pressure of a solution made by dissolving 70.0g of glucose, C6H12O6, in enough water to form 400.0mL of solution at 31.0C ? where is the osmotic pressure in atm, M is the molarity, R is Express your answer to three significant figures and include the appropriate units. the ideal gas constant, and T is the kelvin temperature. Osmosis is the movement of solvent molecules, but not solute molecules, through a semipermeable membrane. During osmosis, the solvent passes from the more dilute solution to the more concentrated one. However, if sufficient pressure is applied, The wastewater solution from a factory containing high levels of salts needs to be diluted before it can be released into the environment. Therefore, two osmosis can be stopped and, at still higher pressures, it can be containers of waste solution are separated by a semipermeable membrane and pressure is applied to one container, forcing only water molecules through the reversed. Osmotic pressure is the pressure required to stop tendency for the water molecules to have a net flow back toward the more concentrated solution. What was the applied pressure at the end of this process if osmosis, and it is a colligative property, one that depends on the the final concentrations of the solutions were 0.044M and 0.190M at a temperature of 23C ? number of particles dissolved in solution. The higher the Express your answer with the appropriate units. concentration of dissolved particles, the more pressure that must be exerted to stop or reverse osmosis. Seawater can be desalinated to produce drinking water by reverse osmosis. Also, wastewater with high salt concentrations can be desalinated before being released back into the environment. X Incorrect; Try Again; 3 attempts remaining Osmosis is the movement of solvent molecules, but not solute molecules, through a semipermeable membrane. During osmosis, the solvent passes from the more dilute solution to the more concentrated one. However, if sufficient pressure is applied, osmosis can be stopped and, at still higher pressures, it can be reversed. Osmotic pressure is the pressure required to stop osmosis, and it is a colligative property, one that depends on the number of particles dissolved in solution. The higher the concentration of dissolved particles, the more pressure that must be exerted to stop or reverse osmosis. Seawater can be desalinated to produce drinking water by There are limitations to the amount of pressure that can be applied during reverse osmosis because of the physical nature of the membrane. A membrane has reverse osmosis. Also, wastewater with high salt concentrations been developed that can withstand osmotic pressures, , of up to 1.55105 torr . Calculate the maximum molar concentration of a solution that can be can be desalinated before being released back into the purified by reverse osmosis using this membrane at 25C. environment.
