How many atoms are there in a 1cm cube 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
What is the density of copper if the volume of a sample is 30cm cubed and the mass is 267g?
The copper's density is 8.9 g/cm3
What is denser 1 g of gold or 1 kg of copper?
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.
Compute the density of an 820g sample of pure silicon occupying a 350 cm3 container?
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.
What is the mass of a 350 cm3 sample of pure silicon with density of 2.336 gcm3?
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
The copper cube had a mass of 2.7g and the volume of the copper cube is 1cm to the 3rd power?
this means that copper is 2.7g/cm3
What is the mass in grams of a cube of copper that has a volume of 55.0 cm3?
You need to multiply the volume, by the density of copper.
What is the density for copper mass 5.0g volume 0.56 cm3?
The density of this copper mass is about 8.93 g/cm3
What is the mass of a 27cm3 piece of copper?
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.
What is the density of copper if the volume is 30 cm3 and the mass is 267 g?
The density of the copper is 8.9 g/cm3
What is the density of a metal cube its mass is 0.6g and volume of 1cm3?
If its mass is 0.6 g and its volume is 1 cm3 , then its density is 0.6 g per cm3 .
What is the mass and density of COPPER?
The density of copper is 8.94 grams per cm3. The mass will depend on the volume of the "lump" of copper.
A 10.00 cm3 sample of copper has a mass of 89.6 what is the density of copper?
1
What is the mass density of copper if 6.8 cm3 has a mass of 60.9 g?
Density = Mass/Volume = 60.9/6.8 = 8.96 grams per cm3
How many moles are in a 7.30 cm X 7.30 cm X 7.30 cm cube of copper?
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).
What is the density of copper if 20.5 cm3 has a mass of 178g?
(178)/20.5 = 8.6829 grams per cm3
A cube of Styrofoam is 8.0 cm long on each edge and has a volume of 512 cm3. The mass of the cube of Styrofoam is 51 g. What is the density of the Styrofoam?
.10g/cm3
