How did the membrane's mwco affect the filtration rate?
The molecular weight cut-off (MWCO) of a membrane determines the size of particles or molecules that can pass through it. A higher MWCO allows larger molecules to pass through, resulting in a faster filtration rate as more particles can flow through the membrane. Conversely, a lower MWCO restricts larger molecules from passing through, leading to a slower filtration rate.
Why urea is not able to diffuse through 20 mwco?
Urea has a molecular weight lower than 20 MWCO, so it should be able to diffuse through a 20 MWCO membrane. If urea is not able to diffuse through a 20 MWCO membrane, it may be due to factors like the membrane being damaged or having a different pore size than expected, or the presence of additional physical or chemical barriers that prevent urea diffusion.
Why do you think the urea was not able to diffuse through the 20 MWCO membrane?
The 20 MWCO membrane has a molecular weight cutoff that is lower than the molecular weight of urea, preventing urea from passing through the pores of the membrane. This size exclusion property of the membrane hinders the diffusion of urea molecules across it.
What solute's passed through the 100 MWCO membrane?
using a 100 MWCO membrane means that any element, molecule, ion or particle with a molar mass of less than or equal to 100 will be able to pass through. there is an infinite number of combinations able to pass through. sodium and calcium ions would both pass through for example.
What does g stand for p stand for and s stand for?
"G" in this context could stand for gravity, "p" could stand for pressure, and "s" could stand for speed. These are common scientific variables represented by these letters in equations and formulas.
What does MWCO stand for and definition?
molecular weight cut off
Which MWCO membrane had the greatest filtration rate?
200 MWCO
For NaCl which MWCO membrane provided for the net movement of water without movement of NaCl?
20 MWCO

What dialysis membranes has the largest pore sizes?
200 MWCO

What was the average diffusion rate of urea when the 200 MWCO membrane was used as a barrier?
The average diffusion rate of urea through a 200 MWCO (Molecular Weight Cut-Off) membrane would depend on various factors such as concentration gradient, temperature, and membrane properties. Typically, higher MWCO membranes allow for faster diffusion rates of smaller molecules like urea due to their larger pore sizes. Specific experimental data would be needed to calculate the exact diffusion rate in this scenario.
Why do you think the urea was not able to diffuse through the 20 MWCO membrane?
The 20 MWCO membrane has a molecular weight cutoff that is lower than the molecular weight of urea, preventing urea from passing through the pores of the membrane. This size exclusion property of the membrane hinders the diffusion of urea molecules across it.
Why did Nacl pass through the 50 MWCO and not urea?
Because Na has MW of ~23 and Cl has MW of ~35...both of which are small enough to pass through a molecular weight cut off (MWCO) of 50 (don't add there molecular weights together). urea has ~ MW of 60 so it's too big to cross membrane.
Will glucose and albumin diffuse through 200 MWCO?
Glucose (180 g/mol) will diffuse through a 200 MWCO membrane, as its molecular weight is lower than the cutoff. Albumin (molecular weight around 66 kDa or 66,000 g/mol) will not diffuse through a 200 MWCO membrane, as its molecular weight exceeds the cutoff.
Which solutes were able to pass through the 20 MWCO membrane?
None. The molecules were either too polar or they were too big to be transported.
What solute's passed through the 100 MWCO membrane?
using a 100 MWCO membrane means that any element, molecule, ion or particle with a molar mass of less than or equal to 100 will be able to pass through. there is an infinite number of combinations able to pass through. sodium and calcium ions would both pass through for example.
