The density of Iron (Fe) is 7.9g/cm3, Copper (Cu) is 9.0g/cm3, Silver (Ag) is 10.5g/cm3, and Zinc (Zn) is 7.1g/cm3. Your friend wants to sell you a chain and swears that it's silver. You pour 50 mL of water into a graduated cylinder and add the chain. The new reading is 70mL. You then dry and mass the chain, and find that it's 142g, a. What is the density of the chain?
b. Is the chain made of silver?
c. What other physical properties could help you determine if the chain was silver?
