    Mass of Sodium = 574.75 g

    Mass of Chlorine = 886.25 g

    Explanation:

    The balance chemical equation for the synthesis of NaCl is,

    2 Na + Cl₂ → 2 NaCl

    Step 1: Find out moles of each reactant required,

    According to balance chemical equation,

    2 moles of NaCl is produced by = 2 moles of Na

    So,

    25 moles of NaCl will be produced by = X moles of Na

    Solving for X,

    X = 25 mol * 2 mol / 2 mol

    X = 25 moles of Na

    Similarly for Cl₂,

    According to balance chemical equation,

    2 moles of NaCl is produced by = 1 mole of Cl₂

    So,

    25 moles of NaCl will be produced by = X moles of Cl₂

    Solving for X,

    X = 25 mol * 1 mol / 2 mol

    X = 12.5 moles of Cl₂

    Step 2: Convert each moles to mass as;

    Mass = Moles * Atomic Mass

    For Na,

    Mass = 25 mol * 22.99 g/mol

    Mass = 574.75 g

    For Cl₂,

    Mass = 12.5 mol * 70.90 g/mol

    Mass = 886.25 g
