01/11/17 page 2 Experiment ResultsPredict Question:Predict Question 1: The molecular weight of urea is 60.07. Do you think urea will diffuse through the 20 MWCO membrane? Predict Question 2: Recall that glucose is a monosaccharide, albumin is a protein with 607 amino acids, and the averagemolecular weight of a single amino acid is 135 g/mole.Which of the following will be able to diffuse through the 200 MWCO membrane? Stop & Think Questions:The reason sodium chloride didn't diffuse left to right is that Glucose is a six-carbon sugar. Albumin is a protein with 607 amino acids. The average molecular weight of a single aminoacid is 135 g/mole. There is no reason to run these solutes at the 20 MWCO because The rate of diffusion for urea Experiment Data: Solute MWCO Left Solute Concentration Right Solute Concentration Average Diffusion Rate Na+ Cl- 20 9.00 0.00 0.0000 Urea 20 0.00 0.00 0.0000 Albumin 20 0.00 0.00 0.0000 Glucose 20 0.00 0.00 0.0000 Na+ Cl- 20 0.00 0.00 0.0000 Urea 20 9.00 0.00 0.0000 Albumin 20 0.00 0.00 0.0000 Glucose 20 0.00 0.00 0.0000 Na+ Cl- 50 9.00 0.00 0.0150 Urea 50 0.00 0.00 0.0000 Albumin 50 0.00 0.00 0.0000 Glucose 50 0.00 0.00 0.0000 Na+ Cl- 50 18.00 0.00 0.0273 Urea 50 0.00 0.00 0.0000 Albumin 50 0.00 0.00 0.0000 Glucose 50 0.00 0.00 0.0000 Na+ Cl- 100 9.00 0.00 0.0150 Urea 100 0.00 0.00 0.0000 Albumin 100 0.00 0.00 0.0000 Glucose 100 0.00 0.00 0.0000 Na+ Cl- 100 0.00 0.00 0.0000 Urea 100 9.00 0.00 0.0094
