Balanced equation. Chlorine gas limits and drives the reaction.
2NaI + Cl2 --> 2NaCl + 2I
6.00 moles NaCl (1 mole Cl2/2 mole NaCl)(70.9 grams/1 mole Cl2)
= 213 grams chlorine gas needed
======
How many grams of chlorine gas must be reacted with excess sodium iodide to produce 6.00 moles of sodium chloride?
