Answer
Based on the previous we can say that: The law of conservation of the mass states that the total mass will always stay the same during a chemical reaction. After the reaction, the vessel will have a mass equal to the initial 245 g.
Explanation
The Law of Conservation of Mass states that the mass is neither created nor destroyed in chemical reactions. This means the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction.
Based on the previous we can say that: The law of conservation of the mass states that the total mass will always stay the same during a chemical reaction.
After the reaction, the vessel will have a mass equal to the initial 245 g.
