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 11.53 grams of the compound were dissolved in 218.3 grams of water, the solution began to freeze at -0.287 °C. The compound was also found to be nonvolatile and a non-electrolyte. What is the molecular weight they determined for this compound? ??? g/mol
