Answer:
d. 117 grams
Explanation:
The mass of the table salt produced will be 117 grams.
Chemical reactions obey the law of conservation of mass. In this regard, matter is neither created nor destroyed in the course of a chemical reaction. It is expected that the mass of the reactants and products remain the same.
The reaction expression:
2Na + Cl₂ → 2NaCl
So, mass of sodium = 46g
mass of chlorine formed = 71g
Mass of NaCl = 46 + 71 = 117g
