Na2SO4 <--- 4 atoms of oxygen in one molecule
3 molecules of 4 atoms = 12 atoms of oxygen
3*Na2= 6 3*S= 3 3*O4=12 21 atoms total
There are 6.022x10^23 atoms in one mole of oxygen, or Avogadro's number.
There are three oxygen atoms in sodium hypochlorite (NaClO).
There are 27 hydrogen atoms in retinol (C₢₂₀H₃₀O).
There are 2 oxygen atoms in 1 formula unit of sodium chlorite (NaClO2)
3*Na2= 6 3*S= 3 3*O4=12 21 atoms total
Multiply the coefficient times the subscript for each element. For 3Na2SO4, there are a total of 6 sodium atoms, 3 sulfur atoms, and 12 oxygen atoms.
Fe3O4 has a total of 7 atoms, with 3 iron atoms (Fe) and 4 oxygen atoms (O).
6.
There are 3 atoms in a molecule of water, 2 hydrogen (H) atoms and 1 oxygen atom (O). H2 O
There are 4 atoms in Fe2O2: 2 atoms of iron (Fe) and 2 atoms of oxygen (O).
There are 10 atoms in Fe2O4 - 2 iron (Fe) atoms and 8 oxygen (O) atoms.
1 mole H2SO4 x 4 moles O/mole H2SO4 x 6.02x10^23 atoms of O/mole O = 2.4x10^34 oxygen atoms
The balanced chemical equation for the reaction is 2Na3PO4 + 3CaSO4 ----> Ca3(PO4)2 + 3Na2SO4.
1mol O = 16.0g (rounded to 1 decimal place) 1mol O atoms = 6.022 x 1023 atoms 16g O x 1mol/16g = 1mol O 1mol O x 6.022 x 1023atoms/mol = 6.022 x 1023 atoms O
There are 6.022x10^23 atoms in one mole of oxygen, or Avogadro's number.
1 molecule C6H12O6 = 6 atoms O, so : 36.00*1023 atoms O
