Question

The beverage "soda pop” is made by compressing 85% carbon dioxide mixture, under a total pressure of 64.5 psi, into an aqueous syrup. The Henry's constant for carbon dioxide is 2.3 x 10-2 mole/ (liter * atm). The concentration of CO2 in soda pop is: (a) 0.072 M (b) 0.086 M (c) 0.092 M (d) 0.057 M

Answer 1

Pressure of 202 = 85 23 x 64.5 psi [1 psi => 0.068 alm] = 54.825 psi = 54,825*0.068 atm = 3.7281 alin concentration = KH XP l KH = Henry constant] = 2:3x10 mod atm' x 3:7281 atry = 0.086 mol 1 = 0.086M Concentration of coz in soda pop is 0.086M Hence;
