One technique for studying the energetics of protein structure is to monitor the struc-ture of the protein as a function of the osmotic pressure. In these experiments the os-motic pressure of the solution is varied by using polymers of different molecular weightand concentration. In an experiment poly(ethylene glycol) (PEG) with a molecularweight of 1000.0 g mol- was used. What concentration of PEG is needed tocreate an aqueous solution with an osmotic pressure of 150.0 Pa at 25°C?You may assume that PEG is uncharged and that it does not dissociate or aggregate.

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.

Question

One technique for studying the energetics of protein structure is to monitor the struc-
ture of the protein as a function of the osmotic pressure. In these experiments the os-
motic pressure of the solution is varied by using polymers of different molecular weight
and concentration. In an experiment poly(ethylene glycol) (PEG) with a molecular
weight of 1000.0 g mol- was used. What concentration of PEG is needed to
create an aqueous solution with an osmotic pressure of 150.0 Pa at 25°C?
You may assume that PEG is uncharged and that it does not dissociate or aggregate.
