1. Determine the molar mass of chlorine gas (Cl₂):
* The atomic mass of chlorine (Cl) is approximately 35.45 g/mol.
* Since chlorine gas exists as a diatomic molecule (Cl₂), its molar mass is 2 * 35.45 g/mol = 70.90 g/mol.
2. Use the formula: moles = mass / molar mass
* moles = 47 g / 70.90 g/mol
* moles ≈ 0.66 mol
Therefore, there are approximately 0.66 moles in 47g of chlorine gas.
