A 17.2 mg sample of a protein is dissolved in water to make a 24.9 mL solution.  The osmotic pressure is 0.50 mmHg at 22oC.  What is the molar mass of the protein? Answer with 0 decimal places.

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.

Which solution is the hypertonic solution? And What is the direction of osmotic pressure (n)? NaCI NazSO4 3.0 M 1.0 M Membrane Revell, Introductory Chemistry, 1e, © 2018 W. H. Freeman and Company NaCl solution is the hypertonic solution, A goes from the right compartment to the left. NaCl solution is the hypertonic solution, n goes from the left compartment to the right. Na,SO4 solution is the hypertonic solution, goes from the right compartment to the left. Na2SO4 solution is the hypertonic solution, goes from the left compartment to the right.

There is a 15.85% by mass KCl (molecular mass is 74.5513 g mol) solution at 25°C. The density of the solution is 1 g ml. The Kb for water is 0.513 °C m^-1 the Kf for water is 1.86°C the vapor pressure of pure water is 0.0313 atm.    Could you please help me find the osmotic pressure in atm? I'm so lost

A protein solution consisting of 12.3 mg of protein in 5.00 mL of solution has an osmotic pressure of 1.21 x 10-3 atm at 27 °C. What is the molar mass of the protein to two significant figures? none of the answers are correct 6.8 x 104 g/mol 6.2 x 104 g/mol 4.0 x 104 g/mol

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

✓mall amount of acetonitrile (CH₂CN) is dissolved in a large amount of water. Imagine separating this process into the four stages sketched below. (These sketches show only a portion of the substances, so you can see the density and distribution of atoms and molecules in them.) CH₂CN 98 B H₂O Use these sketches to answer the questions in the table below. The enthalpy of solution AH soln is negative when CH3CN dissolves in water. Use this information to list the stages in order of increasing enthalpy. Would heat be absorbed or released if the system moved from Stage A to B? What force would oppose or favor the system moving from Stage A to B? Check all that apply. 0 O absorbed O released O neither absorbed nor released none Olonic bonding force O covalent bonding force metal bonding force Ohydrogen-bonding force dipole force ion-dipole force Odispersion force 0.0. X solution. S

Which solution has the lowest boiling point?

At 25.0 °C, 100.0 mL of an aqueous solution containing 45.2 mg of a molecular solute has an osmotic pressure of 18.4 Torr. The molar mass of the solute is ___ g/mol.
