The molar mass of hydrochloric acid (HCl) is approximately 36.46 grams per mole.
This calculation is derived from the atomic weights of its constituent elements:
- Hydrogen (H) has an atomic mass of about 1.01 g/mol.
- Chlorine (Cl) has an atomic mass of about 35.45 g/mol.
To find the molar mass of HCl, simply add these two values together:
1.01 g/mol + 35.45 g/mol = 36.46 g/mol
Thus, the molar mass of hydrochloric acid is a critical value to know in chemistry, especially for stoichiometric calculations in reactions involving this strong acid.
