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

girl imma just put my comment here because i need a couple point okurrttt

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
