An aqueous solution has a normal boiling point of 103 c. What is the freezing point of his solution? For Water Kb= 0.51 C/m and Kf= 1.86 C/, I want the answer with datels please!!
What is the freezing point of an aqueous 1.00 m NaCl solution? (Kf = 1.86 *C/m) (Assume complete dissociation of the salt.) I know the answer is -3.78*C but I cannot figure out how to get it. I keep getting -1.86*C. Please show step by step so I can understand. Thank you.

Please show thoroughly as to how you solve it include the formulas, and why it was solved that way. Also be sure I can read and understand the numbers 550 g of NaCl completely dissolves in 1.50 kg of water. Determine the freezing point of this solution. For water, Kf=1.86°C/m. You MUST show all your work to receive credit on this problem. (12 points)
If 15.0g of AlClsubscript(3) were added to the ice-water mixture, what would be the freezing point of the solution? Assume the experimental volume of solution was 65.3 mL, the experimental freeing point of solvent water was 0.5 degrees C, and Ksubscript(f) was 1.86 degreesC/M. Please show all work and math, this is for a lab report. Thank you!!
