About 150.2 grams of Copper.
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
The copper's density is 8.9 g/cm3
1 kg of copper is denser than 1 g of gold because density is defined as mass per unit volume. Since 1 kg of copper has a larger mass compared to 1 g of gold, it will occupy a smaller volume, making it denser.
Density is calculated as mass divided by volume. In this case, the mass is 820g and the volume is 350 cm3. Density = 820g / 350 cm3 ≈ 2.34 g/cm3.
Start by writing the formula that you probably know for density D=m/V Now plug in the data that you have: 2.336 g/cm3 = m/350 cm3 so, m = 350 x 2.336 = 817.6 g
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 mass of copper can be calculated using its density, which is approximately 8.96 g/cm3. By multiplying the volume (27 cm3) by the density, you can determine the mass. In this case, the mass of the 27 cm3 piece of copper would be approximately 242.16 grams.
The density of the copper is 8.9 g/cm3
If its mass is 0.6 g and its volume is 1 cm3 , then its density is 0.6 g per cm3 .
The density of copper is 8.94 grams per cm3. The mass will depend on the volume of the "lump" of copper.

Density = Mass/Volume = 60.9/6.8 = 8.96 grams per cm3
To determine the number of moles in a cube of copper, we first calculate the volume of the cube (7.30 cm x 7.30 cm x 7.30 cm) and then convert it to liters. From there, we can use the density of copper (8.96 g/cm³) to find the mass of copper present. Finally, we can convert the mass of copper to moles using the molar mass of copper (63.55 g/mol).
(178)/20.5 = 8.6829 grams per cm3
