A 0.520g sample of an unknown nonelectrolyte compound is dissolved in 4.17g of lauric acid (Kf=3.90C/m). The freezing point depression is determine to be 4.20C. What is the molar mass of the compound? What mass in grams of CH3OH(MM=32.04g/mol) would need to be added to 290.1g of water in order to lower the freezing point of water by 12.0C ? (Kf for water is 1.86C/m)
