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.
