#4 on your handout "Chemistry - First day’s assignment Fall 2010 (file MISC)"
Help for solving p. 29 1-3
Questions on ------- Density = mass (g) / volume (mL which is same as cm3)
1. They give you both mass (147g) and volume (difference between 20mL and 41mL).
2. They give you Density and g. Plug those numbers in to density formula to find volume (cm3
3. They give you g and cm3. Plug those into the density formula and find density.
      Then compare to density given in Table C on p. 914. Find the density of aluminum. If your density is close to aluminum, it will be pure Al, if not, it is not pure Al.
