Answer:

                     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: <u>Find out moles of each reactant required,</u>

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: <u>Convert each moles to mass as;</u>

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
