I think you mean subatoms, they are the neutron, proton & electron
The molecular formula of pyruvic acid is C3H4O3, which means it has 3 atoms of Carbon, 4 atoms of Hydrogen and 3 atoms of Oxygen. 10 atoms in total.
15 Fe2O3 has 2 + 3 atoms = 5 atoms Multiply the whole thing by 3 and you end up with 15 atoms.
There are a total of 13 atoms in 3Fe(OH)3. This includes 3 iron (Fe) atoms, 9 oxygen (O) atoms, and 3 hydrogen (H) atoms.
There are a total of 17 atoms in 3H3PO4. This includes 3 hydrogen atoms, 3 phosphorus atoms, 12 oxygen atoms, and 1 carbon atom.
It's 3 molecules of water. A water molecule has 3 atoms. So there are 9 atoms in 3H2O
In 3H3PO4, there are 3 hydrogen atoms, 3 phosphorus atoms, 12 oxygen atoms, and 4 additional hydrogen atoms for a total of 19 atoms.
There are 16 atoms in AL2(SO3)3, broken down as follows: 2 atoms of aluminum (Al), 3 atoms of sulfur (S), and 9 atoms of oxygen (O).
15 atoms.
It's 3 molecules of water. A water molecule has 3 atoms. So there are 9 atoms in 3H2O
There are a total of 3 nitrogen atoms in the formula Al(NO3)3.
Fe3O4 has a total of 7 atoms, with 3 iron atoms (Fe) and 4 oxygen atoms (O).
3*Na2= 6 3*S= 3 3*O4=12 21 atoms total
