To calculate the molar mass of hydrochloric acid (HCl), we need to consider the atomic masses of its constituent elements: hydrogen (H) and chlorine (Cl).
The atomic mass of hydrogen is approximately 1.01 g/mol, and the atomic mass of chlorine is about 35.45 g/mol. Since HCl consists of one hydrogen atom and one chlorine atom, we can add their atomic masses together to find the molar mass:
- Atomic mass of H: 1.01 g/mol
- Atomic mass of Cl: 35.45 g/mol
- Molar mass of HCl: 1.01 g/mol + 35.45 g/mol = 36.46 g/mol
Therefore, the molar mass of hydrochloric acid (HCl) is approximately 36.46 g/mol.
