Answer: 8g

Explanation:

The law of conservation of mass explains that the mass of substances before a physical change is the same as the mass after the change i.e mass is always conserved in nature.

Hence, the physical change will convert 8 grams of the reacting substance to 8 grams of products as well.

For instance:

Consider a change: A --> C

Once the mass of "A" is 8g, "C" the product of the physical change will also have a mass of 8g.
