Because of its bat configuration, Batman's body produces excess nitrogen and excretes it as a form of urea, NH2CONH2. The reaction that produces it is the combination of arginine (C6H14N4O2) with the body's water to give urea and ornithine (C5H12N2O2), according to the following reaction: C6H14N4OR2 + H2O → NH2CONH2 + C5H12N2OR2 arginine urea ornithine a. Assuming Batman is a perfect (ideal) machine, his body completely removes the produced urea which is 95 mg of urea; calculate the mass of arginine that must have been used by his body. b. Calculate the mass of ornithine that his body produced. c. If the rest of normal humans are not a perfect machine, it has been established that for this case, the normal human produces 0.0003686 lb of ornithine. What is the reaction efficiency of the normal human body compared to Batman's.
