6.81 grams copper (1 mole Cu/63.55 grams)(6.022 X 1023/1 mole Cu)
= 6.45 X 1022 atoms of copper

Copper phosphate has the chemical formula Cu3(PO4)2. To determine the number of atoms, you need to add up the atoms in each element present. In this case, there are 3 copper atoms, 2 phosphorus atoms, and 8 oxygen atoms, totaling 13 atoms in copper phosphate.
To find the number of atoms in 6.35 g of copper, you first need to determine the number of moles of copper present by dividing the mass of copper by its molar mass (63.55 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms in that number of moles.
Copper(I) oxide (Cu2O) contains 3 atoms: 2 copper atoms and 1 oxygen atom.
A molecule of copper sulfate (CuSO4) contains one copper atom, one sulfur atom, and four oxygen atoms, totaling to a total of six atoms.
To determine the number of Cu atoms in the piece of sterling silver jewelry, you would first need to convert the weight of the jewelry to moles using the molar mass of silver. Then, since sterling silver is typically 92.5% silver and 7.5% copper by weight, you can calculate the number of moles of copper present. Finally, use Avogadro's number to convert from moles to atoms.
Copper phosphate has the chemical formula Cu3(PO4)2. To determine the number of atoms, you need to add up the atoms in each element present. In this case, there are 3 copper atoms, 2 phosphorus atoms, and 8 oxygen atoms, totaling 13 atoms in copper phosphate.
Copper is an element. You can have a single atom or many atoms and it's still copper.
Only one mole of copper.
The answer is 47,128 x 1023 atoms.
To find the number of atoms in 6.35 g of copper, you first need to determine the number of moles of copper present by dividing the mass of copper by its molar mass (63.55 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms in that number of moles.
Copper(I) oxide (Cu2O) contains 3 atoms: 2 copper atoms and 1 oxygen atom.
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.

In one formula unit of copper sulfate (CuSO4), there are three oxygen atoms.
