Compare a 1 M solution of glucose and a 1 M solution of NaCl for osmotic pressure, and  MARK WITH AN "X"  the true statement(s):   glucose contains 6.02 x 1023  particles, NaCl has twice the number of particles (Na+ and Cl-) and twice the osmotic pressure. Osmotic pressure depends on the total number of dissolved particles in the solution, so that ions count as separate particles. glucose contains 6.02 x 1023  particles, NaCl has twice the number of particles (Na+ and Cl-) and both have the same osmotic pressure. both solutions contain 6.02 x 1023 particles, both have the same osmotic pressure.

283.mg of an unknown protein are dissolved in enough solvent to make 5.00mL solution. The osmotic pressure of this solution is measured to be 0.0707atm at 25 degree Celsius. What is the molar mass of the protein. Round your answer to 3 sig-figs.

4. Osmotic pressure is influenced primarily by an osmotic gradient between two solutions which are separated by a semi-permeable membrane. Based on this definition, the osmotic pressure is higher if _______.Choices: Type of solvent used is the same, Osmotic gradient is steeper, Solute concentration is equal, Molarity of solutions is similar
