Molecule of nitrogen has 3 atoms of nitrogen. Nitrogen molecule exist as N3.
A molecule of water (H2O) has 3 atoms: 2 hydrogen atoms and 1 oxygen atom.
There are three carbon atoms and three oxygen atoms in each pyruvate molecule.
3 carbon atoms in a triose phosphate molecule
Each molecule of iron oxide Fe2O3 contains 2 atoms of iron and 3 atoms of oxygen, making a total of 5 atoms in one molecule.
The compound 'Fe2O3' has TWO(2) atoms of iron (Fe) and THREE(3) atoms of oxygen. NB THe number AFTER the elemental symbol indicates the number of atoms of that element present in the compound. Although I cannot show it on 'Answers' , the number should be written 'subscript'. NNB A number written in front(to the left) of a compound indicates the molar ratio required to react. It is written in normal case.
K2O: 3 atoms in the molecule K2O2: 4 atoms in the molecule KO2: 3 atoms in the molecule
The '3' prefix means there are 3 of the molecule. So that means there are 3 times the number of atoms than a single molecule. So, take all the subscripts and multiply them by 3. The answer is simply 12 atoms (3 nitrogens, 9 hydrogens).
there are 11 atoms
There are 12 chlorine atoms in four phosphorus trichloride (PCl3) molecules because each PCl3 molecule contains 3 chlorine atoms. Multiplying 3 chlorine atoms in each molecule by 4 molecules gives a total of 12 chlorine atoms.
Each molecule of SO2 (sulphur dioxide) is made up of three atoms (1 sulphur atom and 2 oxygen atoms).
There are two atoms of nitrogen in each molecule of dinitrogen tetroxide.
18 or 6 maybe 3 *Little black girl voice* That is not my job!
