Explain the CL Molar Mass?

The molar mass of chlorine (Cl) refers to the mass of one mole of chlorine atoms. Its atomic mass is approximately 35.45 g/mol.

Example:
1 mol of Cl atoms = 35.45 g.
For Cl₂ (chlorine gas), the molar mass is 2 × 35.45 = 70.90 g/mol.
 
The molar mass of chlorine (Cl) refers to the mass of one mole of chlorine atoms. For a single chlorine atom, the molar mass is approximately 35.45 grams per mole (g/mol). This value represents the average atomic mass, accounting for the natural isotopic abundance of chlorine isotopes, mainly Cl-35 and Cl-37, found in nature.
 
The molecular weight of Chlorine (Cl) is 35.45g/mol. It implies that a mass of 35.45 grams belongs to a mole of chlorine atoms. The natural state form of chlorine is diatomic (Cl 2), hence its molar mass is about 70.90 g/mol in its gaseous state i.e. chlorine gas (Cl2).
 
The molar mass of chlorine (Cl) depends on the form you're referring to:
  • For a single chlorine atom (Cl):
    The molar mass is approximately 35.45 g/mol.
  • For a chlorine molecule (Cl₂), which is the natural diatomic form of chlorine gas:
    Multiply by 2 → 35.45 × 2 = 70.90 g/mol.
So:
  • Cl = 35.45 g/mol
  • Cl₂ = 70.90 g/mol (used in most chemical reactions involving chlorine gas)
