The oxidation number of iron in this compound is 3. The oxidation numbers of the total oxygen atoms and the total iron atoms must be the same in a neutral compound. There are three oxygen atoms, giving a total for oxygen of 3 X 2 = 6. There are only two iron atoms; therefore, each one must have an oxidation number of 6/2 = 3.
First it helps to know the chemical formula of the compound: NH3 The numbers in the subscript indicate the number of atoms of an element in the compound. If there is no number, then it's implied that there is only one. So, there is one atoms of nitrogen and three atoms of hydrogen; for a total of four atoms.
Depends on the compound. The formula of that compound will tell you how many atoms are in it. Some compounds are pretty simple, like water. The formula for water is H2O. That means 2 hydrogens and 1 oxygen (no subscript means 1.) So, two different types of atoms for a total of three. Or, you might have a compound with the formula of C8H10N4O2. That's caffeine. Count up all the subscripts for each element and you get a total of 24 atoms in that one. And there are plenty of compounds out there with more than that!
Remember the Avogadro Number. This is the number of atoms in an element or the number of molecules in a compound. for an amount of 1 mole. So 1 mole(Li) it is 6.022 x 10^(23) atoms . In Numbers 602,200,000,000,000,000,000,000
C6H12PO6 has: 6 carbons (C), 12 hydrogens(H), 1 phosphorus(P) and 6 oxygens(O). Add the numbers and you will get the total number of atoms in this molecule; a total of 25.
Assuming that the compound is the one that should have been written as Ca(ClO3)2, the answer can be determined by counting in a properly interpreted formula: one Ca, two Cl, and six O for a total of nine.
The formula is Ca(ClO3)2, so the total number of atoms in the compound is 9.
Ca is calcium, one atom.

Yes, chemical formulas show the number of atoms in a compound. Water is H2O -- two hydrogen atoms bonded to one oxygen atom. Carbon dioxide is CO2 -- one carbon and two oxygen atoms.

Ferric oxide is not a covalent compound, it forms a large ionic lattice.
There is no compound with the formula CHO. However, if you meant a sugar such as glucose, the formula is C6H12O6 . So, the total number of atoms is glucose is 6+12+6 = 24 atoms.
2H2SO does not represent any compound that I recall. The closest match for this that I do recall is Sulphuric Acid with a formula: H2SO4 The total number of atoms in Sulphuric acid is: Hydrogen [2] plus Sulphur [1] plus Oxygen [4] making a total of 7 atoms in all.
In Ca(ClO3)2 there are one calcium atom, two chlorine atom and six oxygen atom. So total of nine atoms
