1. Determine the Molar Mass of Chlorine Gas (Cl₂)
* The atomic mass of chlorine (Cl) is 35.45 g/mol.
* Chlorine gas exists as a diatomic molecule (Cl₂), so the molar mass is 2 * 35.45 g/mol = 70.90 g/mol.
2. Use the Formula:
* mass = moles * molar mass
3. Calculate:
* mass = 0.560 moles * 70.90 g/mol
* mass = 39.70 g
Therefore, the mass of 0.560 moles of chlorine gas is 39.70 grams.
