linoleic acid is an essential fatty acid in the human diet, which means that we need to include this acid as part of a healthful diet. linoleic acid is a major constituent of many vegetable oils, including peanut oil, corn oil, and soybean oil. If the mass of a beaker containing 23.0 mL of linoleic acid is 150.07g, and the mass of the empty beaker is 129.32g, what is the density of linoleic acid?

The concentration of H+ of a solution of NaOH its POH is 11.3 is?
