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.
The freezing point of water, H2O, is 0.000 °C at 1 atmosphere. Kf(water) = -1.86 °C/m In a laboratory experiment, students synthesized a new compound and found that when 10.77 grams of the compound were dissolved in 268.4 grams of water, the solution began to freeze at -1.202 °C. The compound was also found to be nonvolatile and a non-electrolyte. What is the molecular weight they determined for this compound ?
