The molar mass of #HCl# is #36.46*g*mol^-1#.

Explanation:

How did I get that figure. Well, I looked up my Periodic Table, and took the sum of the atomic mass of hydrogen and chlorine: #(1.00794+35.45)*g*mol^-1=???#

#"Avogadro's number"# #=# #6.022xx10^23*mol^-1#. How many individual #HCl# molecules are in a mass of #36.46*g# of the gas?
