 Density
Scratch Paper/Notes:
Length of metal block
3.57 cm
Width of metal block
2.83 cm
Height of metal block
1.75 cm
Mass of metal block
139.00 g
Use the data to identify the metal in the block:
aluminum (density = 2.70 g/cm3)
copper
(density = 8.92 g/cm3)
iron
(density = 7.86 g/cm3)
gold
(density = 19.3 g/cm3)
 Density
The density of gold is 19.3 g/cm3
Length of gold block
4.17 cm
Width of gold block
3.23 cm
Height of gold block
1.15 cm
Mass of metal block
g
Determine the mass of this gold block.
 Comparing Objects
Consider a block of copper (density = 8.92 g/cm3) and a block of
gold (density = 19.3 g/cm3)
If the two blocks have the same volume, then the mass of the copper
block is
the mass of the gold block.
If the blocks have the same mass, then the volume of the copper
block is
the volume of the gold block.
