    105.8 g of Na would be required

    Explanation:

    Let's think the reaction:

    2Na (s) + Cl₂ (g) → 2NaCl (s)

    1 mol of chlorine reacts with 2 moles of sodium

    Then, 2.3 moles of Cl₂ would react with (2.3.2) / 1 = 4.6 moles

    Let's determine the mass of them.

    4.6 mol. 23 g/mol = 105.8 g
