Identify the limiting reactant.
Determine the amount of sodium chloride produced.

(1) Cl₂ is the limiting reactant.

(2) 8.18 g

Explanation:

First we convert the given masses of reactants into moles, using their respective molar masses:

0.070 moles of Cl₂ would react completely with (2 * 0.070) 0.14 moles of Na. There are more Na moles than that, so Na is the reactant in excess while Cl₂ is the limiting reactant.

Then we calculate how many moles of NaCl are formed, using the limiting reactant:

Finally we convert NaCl moles into grams:
