The amino acids alanine (mw = 89.1 g/mol) and leucine (mw = 131.2 g/mol) have solubilities of water at room temperature that are reported to be 166 g/l and 24 g/l respectively. calculate the molar solubilities of each of these compounds. write the structure for each amino acid and explain the trend in molar solubility in terms of the structure of the two amino acids. in microscale extractions you are instructed to remove the lower phase using a pasteur pipette even when the organic phase is the top phase. explain why this results in better phase separation than removing the top phase directly with the pasteur pipette
