To calculate the molar mass of hydrochloric acid (HCl), you need to sum the atomic masses of its constituent elements, hydrogen (H) and chlorine (Cl).
- The atomic mass of hydrogen (H) is approximately 1.01 g/mol.
- The atomic mass of chlorine (Cl) is approximately 35.45 g/mol.
Now, you can calculate the molar mass of HCl:
\[
\text{Molar mass of HCl} = \text{mass of H} + \text{mass of Cl}
\]
\[
\text{Molar mass of HCl} = 1.01 \, \text{g/mol} + 35.45 \, \text{g/mol} \approx 36.46 \, \text{g/mol}
\]
Therefore, the molar mass of HCl is approximately 36.46 g/mol. This value is used to calculate the grams of HCl produced from a given amount of reactants (H₂ and Cl₂) in a chemical reaction.
- The atomic mass of hydrogen (H) is approximately 1.01 g/mol.
- The atomic mass of chlorine (Cl) is approximately 35.45 g/mol.
Now, you can calculate the molar mass of HCl:
\[
\text{Molar mass of HCl} = \text{mass of H} + \text{mass of Cl}
\]
\[
\text{Molar mass of HCl} = 1.01 \, \text{g/mol} + 35.45 \, \text{g/mol} \approx 36.46 \, \text{g/mol}
\]
Therefore, the molar mass of HCl is approximately 36.46 g/mol. This value is used to calculate the grams of HCl produced from a given amount of reactants (H₂ and Cl₂) in a chemical reaction.
