WebAlthough both reserpine and raubasine contain a 16-alpha carboxylic acid methyl ester moiety, de-esterification of this group does not appear to be a significant metabolic route for reserpine, and is not a rapid route for elimination for raubasine in humans (Owen et al., 1987). 6.5 Elimination by route of exposure Oral ... WebAccording to Henry’s law, for an ideal solution the solubility, Cg, of a gas (1.38 × 10 −3 mol L −1, in this case) is directly proportional to the pressure, Pg, of the undissolved gas above the solution (101.3 kPa in this case). Because both Cg and Pg are known, this relation can be rearranged and used to solve for k .
