Question 1 options: A. The Mole We will use the analogy of an elephant and its body parts to explore the concept of moles of compounds or elements. The elephant and the carbon tetrachloride, CCl4 molecule are the test cases. One elephant has one trunk and four legs One carbon tetrachloride molecule, CCl4, contains one carbon atom and four chlorine atoms 1 amu = 1.6606 x 10-24 g 1 dozen = 12 items 1 mole = 6.022 x 1023 items = Avogadro's Number Critical Thinking Questions: (Give your answers in terms of a number such as 17 or 3.25 x 1015 trunks) 1. How many trunks are found in one dozen elephants?
