Hydrogen chloride (HCl) contain, of course, hydrogen and chlorine in the molecule.
The formula for hydrochloric acid is HCl. Each molecule of hydrochloric acid is composed of one atom of hydrogen and one molecule of chlorine.
The hydrogen will dissolve
HCl has a single bond in between hydrogen and chlorine. Hydrogen's one and only electron is tied up in that bond. Chlorine's other 6 valence electrons are on that side due to chlorine's high electronegativity. So, the chlorine side will be negative and the hydrogen side will be positive. This makes HCl a highly polar molecule.
Correct, HBr is diatomic, it has two atoms, one of hydrogen and one of bromine.
I think you mean HCl and Cl (with an L). HCl is polar because there is a difference in electronegativity between hydrogen (H) and chlorine (Cl). Cl on its own is a single atom and is not bonded to anything for there to be a difference in electronegativity. Cl2 is nonpolar because there is no difference in electronegativity between atoms of the same element.

HCl is a molecule which is made of two atoms - hydrogen and chlorine.

HCl has a single bond in between hydrogen and chlorine. Hydrogen's one and only electron is tied up in that bond. Chlorine's other 6 valence electrons are on that side due to chlorine's high electronegativity. So, the chlorine side will be negative and the hydrogen side will be positive. This makes HCl a highly polar molecule.
Correct, HBr is diatomic, it has two atoms, one of hydrogen and one of bromine.
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.
HCl (with a lowercase L) is the correct formula for hydrogen chloride. HCI is a common way of misspelling that formula.
Hydrogen chloride molecule (HCl) has two atoms.
Their is no electronegativity difference between two atoms of chlorine, but there is a big enough difference between chlorine and hydrogen to have the electron of hydrogen spend more time in the orbital of chlorine than in the hydrogen orbital, thus this molecule is slightly charged on either end (+/-) and therefore polar covalent.
For solutions where there is only one hydrogen atom per molecule (HCl) N is the same as molarity (M). It differs only when there is more than one hydrogen atom per molecule.
