A general chemistry student found a chunk of metal in the basement of a friend's house. To figure out what it was, he used the ideas just developed in class about density.


First he measured the mass of the metal to be 307.3 grams. Then he dropped the metal into a measuring cup and found that it displaced 15.7 mL of water.


Calculate the density of the metal.

Density =

g / mL


Use the table below to decide the identity of the metal. This metal is most likely fill in the blank 2
