About 150.2 grams of Copper.
The copper's density is 8.9 g/cm3
Find the mass of 1 cm3 of copper.density= mass / volumemass= density * volume (density is about 8.96 g cm-3)mass= 8.96 g cm-3 * 1 cm3 = 8.96 gno. of moles = mass / Molar mass =8.96 g / 63.5 g mol-1 = 0.14 molno. of copper atoms in 1 cm3 of copper= 0.14 mol * 6.022 *1023 =8.4 * 1022 atoms
i would like to know too for my chemistry report!
Density of gold: 19,282 g/cm3 Density of copper: 8,96 g/cm3
104.992
this means that copper is 2.7g/cm3
You need to multiply the volume, by the density of copper.
The density of this copper mass is about 8.93 g/cm3
The density of the copper is 8.9 g/cm3
If a bar of copper has a mass of 216g and a volume of 24 cm3 then its density is 9 g/cm.
The density of copper is 8.94 grams per cm3. The mass will depend on the volume of the "lump" of copper.

what is the mass of 1 -centimeter cube of gold
density of 1.5 cm tall and mass of 1.0 g of a cube of a cork=mass/volume of cube== 1.0/(1.5*1.5*1.5)gm/cm3=.2963gm/cm3
Density = Mass/Volume = 60.9/6.8 = 8.96 grams per cm3
The dimensions given for the copper cube make it 7.303 cubic centimeters in volume. To the justified number of significant digits, 7.303 is 389 cm3. The density of copper is given as 8.96 g/cm3 at 20C. Therefore, at that temperature, the mass of the cube would be grams. The gram molar mass of copper is the same as its gram atomic mass, 63.546, and the cube thus contains (3.49 X 104 )/63.456 or 54.9 moles, to the justified number of significant digits.
(178)/20.5 = 8.6829 grams per cm3
