Answer:
The Molar Mass (MM) of the protein is 14318.5g/mole
Explanation:
Number of moles (n) of the protein = mass/MM = 0.16/MM
From the ideal gas equation
PV = nRT
P = 0.138 atm, V = 2ml = 2cm^3, n = 0.16/MM mole, R = 82.057 cm^3.atm/gmol.K, T = 28°C = 28+273 = 301K
0.138 × 2 = 0.16/MM × 82.057× 301
MM = 3951.9/0.276 = 14318.5g/mole
How does molecular size affect to the permeability
of the membrane to that molecules?
So you will try to find out how many
molecules of each kind pass through the membrane per time unit. If molecules
pass faster, it’s highly permeable to that material. Some molecules may not
pass at all, so then it’s not permeable to that material. Then you can put the materials
in order from the lowest to the highest permeability. You can also try to find
a mathematical formula that shows how permeability increases or decreases as size
increases (usually it decreases). Exel is usually helpful to find that formula:
you can make a plot and see if it is linear, exponential, potential, etc. There
are other softwares with a larger variety of graph options tan Excel.

Answer:
Psychology today is best defined as the scientific study of behavior and mental processes. Hope this helps!
It can be done to an extent in a small area, but it takes everyone to protect everywhere.
