Unformatted text preview: 8.26 This answer can be calculated from the solubility data, which will give an answer in mo] -L'1. We then use the solution component of the blood volume to determine the total number of moles present, which can be converted to volume using the ideal gas expression: volume of plasma = 0.45 x 6.0!] L S = k“ >< P: 5.3 x104 mol-L" -atm'1 x 10.00 atm n“: = S x 2.?

The concentration of CO: in solution will thus increase. The factor by which the concentration will increase cannot be predicted, however, because the amount ofCOz present above the solution is unknown, as is the amount of water. (b) If the temperature is raised, the concentration of CO; in solution will decrease; the heat added will favor the escape ofCOz ﬁ-om solution—the reverse process is exothermic. 8.30 The solubility of CD2 can be determined using Henry‘s law: Soc, =kH xP=2.3 ><1EF2 mol‘L"-atm'1><3.00atrn um! =3 3-: 0.240 L=1.1'><1[l'1 mol co, 233 ...
