Predict the solubility of a protein having a molecular weight of 67,000 kg/kg-mole in water if its solubility values in 1.5 M and 2 M ammonium sulfate solutions are 18 g/1 and 6 g/1 respectively. (NOTE: RESPONSE TO REVIEWER'S COMMENT- I am also confused about units. According to some sources MW can be written as kg/kmol or g/mole or lb/lbmole but i have not come across kg/kg mole which is given in this question as well as some other questions...
