One! You may mean to ask how many atoms there are in one molecule of oxygen, in which case the answer is two.
One oxygen molecule is composed of two oxygen atoms bonded together.
7= Hydrogen 2 Sulfur 1 Oxygen 4
There is 1 carbon atom (C) and 1 oxygen atom (O) in a molecule of carbon monoxide (CO).
Chemical name for CaSO4 is calcium sulphate. It has 4 oxygen atoms in 1 molecule. So it has 12 oxygen atoms in 3 molecules.
There are 3 atoms present: 1 sodium (Na), 1 oxygen (O), and 1 hydrogen (H).
There are 2 oxygen atoms in 1 molecule of oxygen.
There are a total of 2 atoms in NO (1 nitrogen atom and 1 oxygen atom).
0, but there is 1 atom of Oxygen in water.
There are a total of 4 atoms of oxygen in K2SO4: 1 from the sulfate (SO4) molecule and 3 from the potassium (K) atoms.
One oxygen molecule is composed of two oxygen atoms bonded together.
1 fomula unit of KOH has 3 atoms: 1 potassium (K), 1 oxygen (O), and 1 hydrogen (H).
1
oxygen is an element. It is made of only atoms. So I guess 1, since 1 oxygen atom is 1 oxygen atoms. However, it has 6 protons and electrons.
Na2HPO4 The number of each type of atoms are:- Sodium(Na) 2 Hydrogen(H) 1 Phosphorus(P) 1 Oxygen(O) 4 ( The answer)
3 oxygen atoms in three molecules of water.- There are 3 total atoms in water, which is H2O. There are 2 hydrogen atoms (H), and 1 oxygen atom (O).
3 oxygen atoms in three molecules of water.- There are 3 total atoms in water, which is H2O. There are 2 hydrogen atoms (H), and 1 oxygen atom (O).
7= Hydrogen 2 Sulfur 1 Oxygen 4
