QUESTION 8 1 points Save Answr What will the solution vapor pressure be for a solution of 9.13 mol of sucrose (C12H22011) dissolved in 1,000L of water at 20.0 °C? The vapor pressure of pure water at 20.0 "C is 17.5 torr QUESTION 9 1 points Save Answer Osmosis is the net motion of a solvent toward a region of lower solvent concentration from a region of higher solvent concentration. Or otherwise stated: the net movement of a solute from a region of higher solute concentration to a region of lower solute concentration. The important concept is that nature tries to disperse the solutes in a heterogeneous (liquid or gas phase) solution to produce homogeneous solution. This leads to a pressure that propels the components of the mixture. The equation used to describe this pressure is similar to the ideal gas law: TV InRT where n,R, T, and Vhave the same meanings as in the ideal gas law and IT is the osmotic pressure and i is the van't Hoff factor What is the osmotic pressure of 4.84 g of NaCl in 1.00 L of water at 20.0 "C QUESTION 10 1 points What are the units of osmotic pressure in the calculation above? psi atm kPa e All Answers Save and Subm Click Save and Submit to save and submit Click Save All Answers to sove all onswers
