Answer:
After the chemical has completely burned, the total mass of the set up remains being the same than before: 950g.
Explanation:
The mass is conserved during chemical reactions; this is, the mass of the reactants is equal to the mass of the products, so there is not change in mass, and you can conclude quickly that the mass of the set up at the end is 950, the same of starting.
