To calculate the mass of chlorine gas, we need to multiply the number of moles (0.0550 moles) by the molar mass of chlorine gas.

The molar mass of chlorine (Cl₂) is 70.906 g/mol.

Mass = Number of moles × Molar mass
Mass = 0.0550 moles × 70.906 g/mol

Calculating the result:
Mass = 3.9493 g

Answer: The mass of chlorine gas that participates in the chemical reaction is 3.9493 g.
