Answer :
Final answer:
The molar mass of HCl is calculated by adding the atomic mass of hydrogen (1u) and chlorine (35.5u), resulting in a molar mass of 36.5 grams per mole.
Explanation:
To calculate the molar mass of HCl (hydrochloric acid), you need to add the atomic masses of its constituent elements, hydrogen (H) and chlorine (Cl).
- The atomic mass of hydrogen (H) is approximately 1 atomic mass unit (u).
- The atomic mass of chlorine (Cl) is approximately 35.5 atomic mass units (u).
Now, add these atomic masses together to find the molar mass of HCl:
Molar mass of HCl = Atomic mass of H + Atomic mass of Cl
Molar mass of HCl = 1 u + 35.5 u
Molar mass of HCl = 36.5 u
So, the molar mass of HCl is approximately 36.5 grams per mole (g/mol).
