∙ 11y ago
From the density and volume, the mass of this amount of copper is 8.96 grams. There are 63.546 grams in 1 mole of copper, so this is 0.141 moles. There are 6.023 x 10²³ atoms in 1 mole. Multiply this by 0.141 moles = 8.492 x 10²² atoms.

Work out the number of atoms per cm cubed from density?
divide the density of the element by its atomic weight and you'll get the number of atoms per centimeter cubed
How many atoms are present in 6.81g of copper?
6.81 grams copper (1 mole Cu/63.55 grams)(6.022 X 1023/1 mole Cu) = 6.45 X 1022 atoms of copper ----------------------------------------
How many Cu atoms are present in a piece of sterling-silver jewelry weighing 33.14 g?
This depends on the percentage of copper in the alloy.If this alloy contain 7,5 % Cu the number of copper atoms is approx. 0,2355.10.e+23.

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 elements are in copper carbide?
Copper carbide is a salt. As the element implies, the ions present are copper ions and carbide ions. Carbide ions are made of carbon atoms.
How many moles are present in 6.022 x 1023 atoms of Cr?
Only one mole of copper.
How many oxygen atoms are there in a molecule of copper nitrate?
The compound copper nitrate has Cu(NO3)2 for a chemical formula. In that formula, we see that there is an NO3 radical present, and that there are 3 atoms of oxygen in that radical (the sub 3 after the O). But there are 2 of those NO3 radicals (the sub 2 outside of the parens) present in this compound. That means that there are 3 x 2 oxygen atoms in a molecule of copper nitrate, or 6 atoms of oxygen in Cu(NO3)2.
