WebMay 29, 2024 · Calculate the molality of the cetyl alcohol solution and use it to determine the value of the freezing point depression constant, kfp, for BHT. Use the calculated value of kfp, along with the masses of the unknown solute and BHT, to find the molar mass of the unknown solute. molality of cetyl alcohol solution = 0. 5 m kfp of BHT = 4. 0 ? WebJul 29, 2024 · Because 1 mol of ethanol contains 2 mol of carbon atoms (2 × 12.011 g), 6 mol of hydrogen atoms (6 × 1.0079 g), and 1 mol of oxygen atoms (1 × 15.9994 g), its molar mass is 46.069 g/mol. Similarly, the formula mass of calcium phosphate [Ca 3 (PO 4) 2] is 310.177 amu, so its molar mass is 310.177 g/mol.
