a 275mL sample of vapor in equilibrium with 1-propylamine at 25C is removed and dissolved in 0.500L of H20. For 1-propalamine, Kb=3.72*10^-4 and the vapor pressure at 25C is 215 torr.

Question

(a)What should be the pH of the aqueous solution?
(b) How many mg of NaOH dissolved in 0.500L of water give the same pH?

Could you please give the exact steps to go through this problem? (answer too, if you can)thanks

Answer 1

I worked this for someone just a second ago. If not for you, repost at the top of the board and I'll find it to give you a link.
