Chemistry 2 show all work
A solution is prepared by dissolving 7.50 g of glycerin (C_6H_8O_3) in 201 g of ethanol (C_2H_5OH). The freezing point of the solution is ______C. The freezing point of pure ethanol is -114.6 degree C at 1 atm. The molal-freezing-point-depression constant (K_f) for ethanol is 1.99 degree C/m. The molar masses of glycerin and of ethanol are 92.1 g/mol and 46.1 g/mol, respectively. A) -107.4 B) -115.4 C) -113.8 D)-121.8 E) 0.806
