There is only one
a. 1 iron atom per molecule. in total, two atoms
There are 6 atoms of oxygen represented by this.
There are 2 oxygen atoms in 1 molecule of oxygen.
1
Fe + 2x Cl = Fe + Cl + Cl = 3 atoms per molecule.
You meant to say....how many atoms does one molecule have. That will depend. For example..... 1 molecule of CH4 has 5 atoms.......1 molecule of C6H12O6 has 24.....and 1 molecule of H2O2 has 4 atoms. Hope this helps. Dr Jim Romano CEO Orgoman.com
There are 3 atoms of hydrogen in 1 molecule of ethanol (C2H5OH).
Depend on it's valence state. Iron is transition metal and had many possible valence state (e.g. Fe2+ or Fe3+). For the case Fe2+ then it is just FeO and 1 atom informula but if it is Fe3+ then it is Fe2O3 and thus 2 atoms. You must check what written clearly, for iron oxide such as rust, it is wrtten as iron(III)oxide to stand for being a Fe3+.
An ethanol molecule consists of 2 carbon atoms, 6 hydrogen atoms, and 1 oxygen atom. Therefore, there are a total of 9 atoms in an ethanol molecule.
There are 3 atoms in a water molecule (H2O) - 2 hydrogen atoms and 1 oxygen atom.
The formula H2SO4 represents 7 atoms in a molecule: 2 H atoms, 1 S atom, and 4 O atoms.
P4. It has 4 atoms compared to Cl2 having 2
