To calculate the molar mass of sodium chloride (NaCl), you need to look at the molar masses of its constituent elements: sodium (Na) and chlorine (Cl).
The atomic mass of sodium (Na) is approximately 22.99 g/mol, and the atomic mass of chlorine (Cl) is about 35.45 g/mol. To find the molar mass of NaCl, simply add these two values together:
- Molar mass of Na = 22.99 g/mol
- Molar mass of Cl = 35.45 g/mol
Now, perform the addition:
22.99 g/mol + 35.45 g/mol = 58.44 g/mol
Therefore, the molar mass of sodium chloride (NaCl) is approximately 58.44 g/mol.
