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

Nconcentration refers to the molar concentration of an ion in solution. it may be identical to, or greater or less than, the molar concentration of the compound containing the ion that was used to make the solution. for soluble salts, the molarity of a particular ion is equal to the molarity of that compound times the subscript for that ion. for example, 1 m of alcl3 is 1 m in al3+ and 3 m in cl−. 1 m of (nh4)2so4 is 2 m in nh4+ and 1 m in so42−. part a what is the concentration of k+ in 0.15 m of k2s? view available hint(s) nothing m m part b if cacl2 is dissolved in water, what can be said about the concentration of the ca2+ ion? view available hint(s) if is dissolved in water, what can be said about the concentration of the ion? it has the same concentration as the cl− ion. its concentration is half that of the cl− ion. its concentration is twice that of the cl− ion. its concentration is one-third that of the cl− ion. part c a scientist wants to make a solution of tribasic sodium phosphate, na3po4, for a laboratory experiment. how many grams of na3po4 will be needed to produce 550 ml of a solution that has a concentration of na+ ions of 0.700 m ? express your answer numerically in grams. view available hint(s) mass of na3po4 n a 3 p o 4 = nothing g provide feedback
