Consider palmatic acid, C16H32O2, a common fatty acid used in the manufacture of soap: a solution of palmatic acid is prepared by mixing 112 g of palmatic acid with 725 ml of benzene (C6H6) (d = 0.879ml). The density of the resulting solution is 0.902 g/ml. What is the mass percent of palmatic acid in the solution? What is the molarity of the solution ?
