I thank you very much, I believe I really need to see it step by step to understand it. Another thing what did the 100+6.7 have to do with the equation. Also changing the -6.7C to 6.7C is this something that you would do to any boiling or freezing problem
i think I need help setting this up. Not looking for the answer just want to understand it. Than you
not sure where to start. do i use the freezing point depression equation
Thanks I under stank Kf but in my book it says that Kf is 0.512
what is the boiling point of an aqueous solution that freezes at -67 degrees C? I was given this answer What is 100+6.7 (1.86/.52) ? so 100+6.7 = 106.7 1.86/.52 = 3.58 is the .52 the Kb I got the answer in the book I just don't understand how they got to
im lost where did you get the 52 from
