    Q:

    		 The saponification value of triacylglycerides is a measure of the mass of NaOH required to detach, as sodium salts, the fatty acid chains from 1 gram of the triacylglycerides. Samples A and B have saponification values of 180 mg and 320 mg respectively. Which sample has longer fatty acid chains (on average) and why?
    		 

    A

    		 A because the mass of NaOH required is directly proportional to the mass of fat based on the length of the fatty acid chains

    B

    		 A because the mass of NaOH required is inversely proportional to the mass of fat based on the length of the fatty acid chains

    C

    		 B because the mass of NaOH required is directly proportional to the mass of fat based on the length of the fatty acid chains

    D

    		 B because the mass of NaOH required is inversely proportional to the mass of fat based on the length of the fatty acid chains
