one Hydrogen atom and one Chlorine atom for a total of two
There are two atoms in one molecule of hydrochloric acid. It contains hydrogen and chlorine. H is hydrogen and Cl is chlorine.
6 HCl molecules contain 12 atoms.
Well the atoms are Chlorine (Cl) and Hydrogen (H) and the molecule is HCl which is made of one Chlorine atom and one Hydrogen atom (2 atoms altogether) However the "2" in the front of "HCl" means that there are two molecules of HCl and therefore there are FOUR atoms present.
There are no atoms of HCl in one molecule of HCl, because HCl is not an atom. It is a molecule. HCl is made of two parts: hydrogen atoms, and chlorine atoms. Each molecule of HCl contains one hydrogen atom and one chlorine atom. H stands for hydrogen, and Cl stands for chlorine. Compare this to H2O, which is the chemical formula for water. Water has 2 hydrogen atoms and 1 oxygen atom.
The answer is 2. 1 atom of Hydrogen and 1 atom of Chlorine.
Six moles of HCl will be required: Each mole of chlorine contains two chlorine atoms, but each mole of HCl contains only one chlorine atom and the other reagent noted contains no chlorine atoms.

HCl is a molecule which is made of two atoms - hydrogen and chlorine.
It depends on how many molecules of HCl you have. In one molecule of HCl there are 2 atoms present.

HCl
The answer is 2. 1 atom of Hydrogen and 1 atom of Chlorine.

Divide by molar mass and check the units(italicalized):0.140 (g HCl) / 36.45 (g.mol-1HCl) = 3.84*10-3 mol HCl
In HCl2 are 1+2=3 atoms, so in 2HCl2 are 2*3=6 atoms, HOWEVER this is NOT the formula of an existing compound. HCl (with 2 atoms per molecule) is a real compound formula.
i believe just one. H has a oxidation # of 1 and Cl has an oxidation # of -1. So in one molecule of HCl i think there would be just one. Isnt that almost the same thing as hydrochloric acid though??
Correct, HBr is diatomic, it has two atoms, one of hydrogen and one of bromine.
