Hint:The molecular formula of hydrochloric acid is $HCl$. Hydrochloric acid is a very strong acid. The molar mass of hydrochloric acid will be the sum of the molar masses of hydrogen and chlorine atom.
Complete step by step answer:
Molar mass of a molecule is equal to the sum of the atomic masses of the constituent atoms . Hydrochloric acid is made up of one hydrogen atom and one chlorine atom. The molar mass of hydrogen atom is $1g/mol$ and molar mass of chlorine atom is $35.5g/mol$
Let the molar mass of hydrochloric acid be $M$.
$M = 1 + 35.5 = 36.5g/mol$
So the molar mass of hydrochloric acid is $M = 36.5g/mol$ .
Additional information:
Hydrochloric acid is a very strong acid. It dissociates completely in water into chlorine and hydrogen ions. It has a distinctive pungent smell. Earlier people used to call hydrochloric acid as muriatic acid. Hydrochloric acid is also found in the stomach of human beings. It is secreted by the parietal cells. Hydrochloric acid works to activate pepsinogen, thereby forming an enzyme called pepsin. Hydrochloric acid reacts with sodium hydroxide to produce sodium chloride and water. It is a neutralization reaction. Hydrochloric acid is used to dissolve calcium carbonate. Hydrochloric acid is used in many laboratories to perform many important reactions .
Note:
Always remember that the molecular formula of hydrochloric acid is $HCl$. It is a very strong acid. The molar mass of hydrochloric acid is $M = 36.5g/mol$ . It can cause severe burns if it is not handled with safety precautions. Hydrochloric acid has a distinctive pungent smell.
