when 53.2g Na react with 65.8g Cl2, which one is the limiting reactant ?

Question

2Na + Cl2 —> 2NaCl

1. O2
2. H2O
3. Cl2
4. NaCl
5. Na

Answer 1

Hello, Caitlyn,

Calculate the number of moles provided for both the Na and Cl2. The molar ratio from the equation says we need 1/2 mole of Cl2 for every 1 mole of Na. I found 2.314 moles Na, so 1/2 that would be 1.157 moles Cl2 required to consume all of the Na. But I can only find 0.928 moles of Cl₂, so it must be the limiting reagent.
