[QUOTE="imxaxpunk, post: 2621552, member: 236021"] [h2]Homework Statement [/h2] The henry's law constant (k) for carbon monoxide in water at 25 degree C is 9.71 * 10 ^-4 mol/(L*atm) How many moles of CO will dissolve in 1.00 L of water if the partial pressure of CO is 2.75 atm? [h2]Homework Equations[/h2] waht pressure of carbon dioxide is required to keep the carbon dioxide concentration in a bottle of club soda at .12 M at 25 degrees C? Info: Kh for Co2 at 25 degrees C = 3.4 * 10^-2 M/atm Answer to that is 3.5 atm [h2]The Attempt at a Solution[/h2] s(g) = Kh * Pg Since i don't have the Molarity i have no idea what to do. M = moles solute ( i don't know if the water or CO is the solvent or solute) divided by L solution (9.71*10^-4mol/L*atm)(2.75 atm) = 2.67 *10^-3 mol/L 2.67*10^-3 mol/L * 1.00 L = 2.67*10^-3 mol i have no idea what to do from there [/QUOTE]
