please help me with those wuestions.

Part 3-Density Trends in a Group Silicon (Si), tin (Sn), and lead (Pb) are all in the same group. The density of silicon is about 233g/cm2 and the density of PD is 11.34g/cm : Based on this trend, what do you estimate about the density of tin? Determine the density of tin. Use the water displacement technique to find the density. Use a large piece of tin, not the small pieces in the fume hood. Data Mass of sample 32.87508 Volume of sample of tin Do your results support your estimate? Explain. When elements are organized in the periodic table, various trends appear. Describe some of the trends that you learned about from this lab
