chemistry
I see your error. You used the incorrect freezing point depression constant: .52 instead of 1.86.
chemistry
This sounds like solid reasoning, but I apologize, because the answer in the back of my textbook says 0.56 mL of 12.0 M HCl.
chemistry
PLEASE SHOW PROCEDURE! You wish to prepare an aqueous solution that has a freezing point of -0.100 degrees Celsius. How many milliliters of 12.0 M HCl would you use to prepare 250.0 mL of such a solution? [Hint: Note that in a dilute aqueous solution, molality and molarity are...
