Answer: 25g

Step-by-step explanation:

Although mass can be rearranged or change in form, it cannot be created or destroyed during a chemical reaction. In short, the total mass of the starting materials (reactants) will equal the mass of the product. This statement summarizes the Law of Conservation of Mass
