Answer:
180 g
Step-by-step explanation:
At the end of the reaction, the mass is still expected to be 180g this is because in every chemical reaction, mass must be conserved.
According to the law of conservation of mass "in a chemical reaction, matter is neither created nor destroyed".
- Bonds are broken and elements rearranged.
- The mass is thereby constant
- The sum of the mass of the reactant is then even equal to the mass of the product derived.
