Hint: The molar mass of a compound is specified by the sum of the usual atomic weight (namely, the ordinary relative atomic mass) of the atoms which method the compound multiplied by the molar mass constant. Multiplying by the molar mass constant type assures that the scheming is dimensionally accurate: standard relative atomic masses are dimensionless amounts (i.e., pure numbers) while molar masses have units (in this case, grams/mole).

Complete step by step answer:
The sum of the atomic mass of hydrogen and chlorine: $\left( {1.00794 + 35.45} \right) \cdot g \cdot mo{l^{ - 1}} = {\text{ }}36.46 \cdot g \cdot mo{l^{ - 1}}$ .
Avogadro's number $= \;6.022 \times {10^{23}} \cdot mo{l^{ - 1}}$ . The specific $HCl$ molecules are in a mass of $36.46 \cdot g\;$ of the gas.
The molar mass of $HCl$ is $36.46 \cdot g \cdot mo{l^{ - 1}}$ .

The compound Hydrogen Chloride has the chemical formula $HCl$ .Hydrogen chloride $\left( {{{HCl}}} \right),$ a compound of the elements hydrogen and chlorine, a gas at room temperature and pressure. A resolution of the gas in water is called Hydrochloric Acid.
At all times use the upper case for the first character in the element name and the inferior case for the second character as in the periodic table. Equate: ${{Co}}$ - cobalt and ${{CO}}$ - carbon monoxide. Therefore, ${{N}}{{{a}}_{{3}}}{{P}}{{{O}}_{{4}}}$ — correct notation, ${{na3po4}}/{{NA3PO4}}$ — incorrect notation.
