Kf Of Lauric Acid. Web freezing point depression is a colligative property observed in solutions that results from the introduction of solute molecules to a solvent. The salts and esters of.
Obtain about 8 g of lauric acid and place it in a clean dry test tube. It is found in many vegetable fats and in coconut and palm kernel oils. Record the mass of the lauric acid in the data sheet. It is a bright white, powdery solid with a faint odor of bay oil or soap. Typically, saturated fats are considered to be bad for your health. Web the results of a 2009 study found that lauric acid could reduce inflammation and the number of bacteria present. A 0.520 g sample of an unknown nonelectrolyte compound is dissolved in 4,31 g of lauric acid (kf = 3.90 °c/m). People also use it as medicine. The freezing points of solutions are all lower than that of the pure solvent and is directly proportional to the molality of the solute. The salts and esters of.
What is the molar mass of the compound? The salts and esters of. (1) δ t f = t f ( s o l v e n t) − t f ( s o l u t i o n) = k f. Web the results of a 2009 study found that lauric acid could reduce inflammation and the number of bacteria present. 1.08 = moles of the solute/ 0.00402 kg ( 4.02 grams of the solvent is divided by 1000 to get kilograms) to get the moles of the solute multiply the molality with the kg of the solvent. What is the molar mass of the compound? Web 1 expert answer. The freezing points of solutions are all lower than that of the pure solvent and is directly proportional to the molality of the solute. Prepare a mixture of lauric acid and benzoic acid. It is a bright white, powdery solid with a faint odor of bay oil or soap. Obtain about 8 g of lauric acid and place it in a clean dry test tube.
