phy/chem for SUBBU

HERE

I have a lap report as well as post questions for my chemistry lab class.
That’s due Friday Oct/2 by midnight.
All I need your help with please is a one page lab report about the Density Relationships (See link for more info)
Also, please answer the three questions blew in one to 2 pages.
1. The density of lead is 11.3 g/mL. What is the density of a 2 foot long piece of 1 inch diameter lead pipe? What is the density of a one inch piece of this pipe?
2. A can of regular Coca-Cola sinks in a tub of water. A can of Diet-Coke floats in the water. What can you conclude from these observations about the relative densities of these cans? What could possible cause a difference in the densities of the two cans of soda?
3. Our bodies are a very irregular shape. Propose a method to determine the density of your body.

Please see the link for more info about we’ve done
