Adrenaline is a hormone released in response to mental and physical stress. A solution is prepared with 1.500g of adrenaline in157g of CCl4 where Tf = -22.3 degree Celsius and Kf=29.8 C/m and the freezing point of the solution was determined experimentally to be -23.7 degrees Celsius,
Calculate the freezing point depression and determine the molality of solution and molar mass of the solute.
