electrical force exists between electron and nucleus
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
40,000 of them.
depends on how big the cube is
9210 cm^3.
Copper is an element. You can have a single atom or many atoms and it's still copper.
If it is a centimetre cube then, by definition, its edge is 1 centimetre.
A cubic centimeter is the volume of a cube that measures one centimeter on each side.
The answer is 47,128 x 1023 atoms.
There are no "atoms in an element," but rather atoms OF an element. If you are trying to find the number of atoms in a sample of a pure element you divide its weight by its molar mass and then multiply by 6.022 x 10^23 to get the answer in atoms. The answer options are 2,3, or 4.
That depends on the density of the material you are experimenting with.
You need 0.003375 of one cube.
10*10*10 = 1000 cubic centimetres
