What is the molar mass of BaCl2?

Answer 1

To calculate the molar mass of barium chloride (BaCl₂), we need to sum the molar masses of its constituent elements: barium (Ba) and chlorine (Cl).

1. Molar mass of barium (Ba): Approximately 137.33 g/mol.
2. Molar mass of chlorine (Cl): Approximately 35.45 g/mol.

Since BaCl₂ contains one barium atom and two chlorine atoms, we can calculate the molar mass as follows:

\[ \text{Molar mass of BaCl}_2 = \text{Molar mass of Ba} + 2 \times \text{Molar mass of Cl} \]

\[ \text{Molar mass of BaCl}_2 = 137.33 , \text{g/mol} + 2 \times 35.45 , \text{g/mol} \]

\[ \text{Molar mass of BaCl}_2 = 137.33 , \text{g/mol} + 70.90 , \text{g/mol} \]

\[ \text{Molar mass of BaCl}_2 = 208.23 , \text{g/mol} \]

Thus, the molar mass of BaCl₂ is approximately 208.23 g/mol.
