A molecule is a combination of atoms. To know how many atoms are in one molecule, you have to find out what atoms are in the molecule.
Hydrogen Sulfide has a total of three atoms. Hydrogen has two, and Sulfur has one. H2S.
In one Ag2O there are 2 'Ag' (silver) atoms and 1 'O' (oxygen) atom: three in total
NaHSO4 is a compound known as sodium hydrogen sulfate or sodium bisulfate. It has one sodium atom, one hydrogen atom, one sulfur atom and four oxygen atoms for a total of seven atoms.
CCl is not an existing, possible compound. However it should have two atoms in total, one C (= Carbon) and one Cl (= Chlorine) atom.
The formula unit is Ag2SO4, which contains two silver atoms, one sulfur atom, and four oxygen atoms for a total of seven atoms.
Two hydrogen atoms and one oxygen atom
3
The total no. of atoms present in C12H22O11 is 45.
There are a total of 6 atoms in this formula - one copper, one sulfur and four oxygen atoms.
2
2Hg atoms and 2Cl atoms for a total of 4 atoms.
3 atoms. 1 carbon atom and 2 oxygen atoms.
Ni(OH)2 1 atom of nickel 2 atoms of oxygen 2 atoms of hydrogen -------------------------------+ total atoms = 5 atoms
One PCl3has one phosphorus (P) and three chlorine (Cl) atoms, so a total of 4 atoms.So, 3PCl3has three phosphorus (P) and nine chlorine (Cl) atoms, so a total of 12 atoms.
total 5 atoms 2 of Mg and 3 of O
KClO3. So there is one potassium, one chlorine and three oxygen atoms. A total of 5 atoms.
In one molecule of water there are 3 atoms. One oxygen atom and two hydrogen atoms.
