One mole of oxigen (O2-the diatomic molecule) is needed for 127,092 g copper to form CuO.
Well, honey, in one mole of copper II sulfate, there are 4 moles of oxygen atoms. So, if you're asking about moles of oxygen molecules (O₂), then the answer is 8 moles. But if you're talking about individual oxygen atoms, then it's 4 moles. Either way, you've got a whole lotta oxygen hanging out with that copper II sulfate.
There are 3 moles of S atoms in 120.0g of Copper(II) Sulfate. In one mole of Copper(II) Sulfate, there are 4 moles of oxygen atoms, 1 mole of sulfur atoms, and 1 mole of copper atoms. Since the molar mass of Copper(II) Sulfate is 159.61 g/mol, the molar mass of sulfur is 32.065 g/mol. Hence, there are 3 moles of sulfur atoms in 120.0g of Copper(II) Sulfate.
There are 4 phosphorus atoms in one molecule of copper phosphate (Cu3(PO4)2). Therefore, in 7.6 moles of copper phosphate, there would be 7.6 moles x 4 atoms = 30.4 moles of phosphorus atoms.
To find the number of moles of copper atoms, divide the number of copper atoms by Avogadro's number (6.022 x 10^23). Therefore, for 1.2 x 10^48 copper atoms, the number of moles is 1.99 x 10^24 moles.
There are twice as many oxygen atoms as carbon atoms in carbon dioxide, so 100.0 moles of carbon dioxide would contain 200.0 moles of oxygen atoms.
In 0.800 moles of MgO, there are the same number of oxygen atoms as there are in 0.800 moles of O atoms. One mole of MgO contains one mole of oxygen atoms, which is equivalent to 6.022 x 10^23 oxygen atoms.
0.75 moles of any substance is 0.75(6.02x1023) = 4.52x1023 particles. If those particles are CO2 molecules, and each molecule has 2 oxygen atoms, then it's 2(4.52x1023) = 9.04x1023 oxygen atoms.
5,26 moles of oxygen contain 31,676.10e23 atoms.
In diphosphorous pentoxide (P4O10), there are 10 oxygen atoms for every molecule. Therefore, in 5.00 moles of diphosphorous pentoxide, there would be 5.00 moles x 10 oxygen atoms = 50.0 moles of oxygen atoms.
There are 10 moles of oxygen in one mole of P4O10. This is because each molecule of P4O10 contains 4 phosphorus atoms and 10 oxygen atoms.
4 moles of oxygen atoms are present in 4 moles of H2O
One mol of copper is 6.02 x1023 atoms. So 3.44 x 1023 would be 0.571 moles.
