Density of Elements

Mon Oct 29

Characteristics of Metals

 

Lab:Identifying metals based on their Density

 

Analysis

1. Rank the metals based on their densities. Use this ranking to determine which metal is which.  Al 2.7g/cm3

Fe 7.87 g/cm3    Brass 8.73g/cm3  Cu 8.9 g/cm3

2. Calculate the density of each metal. Determine which metal is which.

3.a)  Calculate your percent accuracy.

Read 5.6 p 192-193  Q 3-10 & 12 p 198

b) Provide explanations for the inaccuracy based on possible experimental errors.

 

Extra: Watch the following tutorials on Density. 
What is the significance of the Gold Crown?  How was density used to solve the king's problem?
