Butylated hydroxyanisole (BHA) is used as an antioxidant in margarine and other fats and oils; it prevents oxidation and prolongs shelf life of the food. What is the molar mass of BHA if 0.640 grams of the compound, dissolved in 25.0 grams of chloroform, produces a solution whose boiling point is 62.22 degrees Celsius? The normal boiling point of chloroform is 61.70 degrees Celsius and Kbp for chloroform is +3.63 degrees Celsius/m.
