How many grams are in a mole of hydrogen chloride?

The molar mass of hydrogen chloride (HCl) can be calculated by adding up the atomic masses of hydrogen (H) and chlorine (Cl).

The atomic mass of hydrogen (H) is approximately 1.008 grams per mole, and the atomic mass of chlorine (Cl) is approximately 35.453 grams per mole.

So, to find the molar mass of hydrogen chloride (HCl), we add the atomic masses of hydrogen and chlorine:

Molar mass of HCl = $(1 \times atomic mass of H) + (1 \times atomic mass of Cl)$
$= (1 \times 1.008 g/mol) + (1 \times 35.453 g/mol)$
$= 36.461 g/mol$

Therefore, there are approximately 36.461 grams in one mole of hydrogen chloride (HCl).
