How many atoms in cu(OH)2?
There are 5 atoms in one molecule of Cu(OH)2, comprising one copper (Cu) atom, two oxygen (O) atoms, and two hydrogen (H) atoms.
How many atoms are in CuNO3 2?
Cu(NO3)2 has 9 atoms 1 Cu atom 2 N atoms 6 O atoms
How many atoms are in CU(NO3)2?
There are 11 atoms in one formula unit of Cu(NO3)2: one copper atom (Cu), two nitrogen atoms (N), six oxygen atoms (O), and two nitrogen atoms (N) from the nitrate (NO3) group.
How many Cu atoms are present in a piece of sterling-silver jewelry weighing 33.14 g?
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.
If a reaction starts with 4 Cu atoms 5 O atoms and 10 H atoms what is known about the products?
Since there are more Cu atoms than O or H atoms in the reactants, it is likely that Cu will be the limiting reactant in the reaction. This means that there will likely be leftover O and H atoms after the reaction is complete. The products will likely contain Cu, O, and H atoms in different ratios based on the stoichiometry of the reaction.
How many Cu atoms are present in 85mol?
To calculate the number of Cu atoms in 85 mol, you need to use Avogadro's number, which is approximately 6.022 x 10^23 atoms/mol. So, for 85 mol of Cu, the number of Cu atoms would be 85 mol x 6.022 x 10^23 atoms/mol = 5.12 x 10^25 Cu atoms.
How may atoms of oxygen are present in Cu(NO3)2?
Copper(II) nitrate has six oxygen atoms.
How many atoms in cu(OH)2?
There are 5 atoms in one molecule of Cu(OH)2, comprising one copper (Cu) atom, two oxygen (O) atoms, and two hydrogen (H) atoms.

Cu(NO3)2 has 9 atoms 1 Cu atom 2 N atoms 6 O atoms
How many oxygen atoms are present in a 14.0 g sample of Cu(NO3)2?
14.0 g x 1 mole/187.56 g = 0.0746 moles0.0746 moles Cu(NO3)2 x 6 moles O/mole Cu(NO3)2 = 0.448 moles O atoms0.448 moles O atoms x 6.02x10^23 atoms/mole = 2.70x10^23 atoms of oxygen
How many moles of atoms are in 450000000000000000000000 atoms of Cu?
Divide that number of atoms by 6.02x10^23 atoms/mole
How many atoms are in each elemental sample 4.0mol Cu?
4.0 moles Cu (6.022 X 1023/1 mole Cu) = 2.4 X 1024 atoms 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.
