The answer is E. But I keep getting A.I know I have to use the osmotic pressure formula, to find M, then with the M change to grams, to find the molality, also use the density to find the kg to find the molality, then with the molality plug it into the Freezing point depression formula. At 298 K, the osmotic pressure of an aqueous glucose solution is 13.2 atm. Calculate the freezing point f the solution. (The density of the solution is 1.037 g/mL. MWt of glucose = 180 g/mole)A) 1.07 C B) 296.9 K C) -1.00 C D) +1.00 C E) 272.08K
