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.
