Explanation:

Step1: Recall law of conservation of mass

In a chemical reaction, the total mass of reactants equals the total mass of products.

Step2: Apply to given reaction

The combined mass of sodium metal and chlorine gas (reactants) is 50 grams. So, the mass of sodium chloride (product) will be 50 grams.

Answer:

B. will be exactly 50 grams.
