A chemical reaction occurs in a closed system to observe and test the Law of Conservation of Mass. A piece of copper metal is placed in a silver nitrate solution in an Erlenmeyer flask. The flask is stoppered, weighed, and observed. The reaction that occurs is Cu(s) + 2 AgNO3(aq) → Cu(NO3)2(aq) + 2 Ag(s). Once the chemical reaction was complete, the system was weighed again. The mass of the reactants is measured to be a total mass of 122.8 g. After the reaction is complete, what will be the mass of products formed? Record only your final answer with the correct number of significant digits and proper units.

Question
A chemical reaction occurs in a closed system to observe and test the Law of Conservation of Mass.

A piece of copper metal is placed in a silver nitrate solution in an Erlenmeyer flask. The flask is stoppered, weighed, and observed.

The reaction that occurs is Cu(s) + 2 AgNO3(aq) → Cu(NO3)2(aq) + 2 Ag(s).

Once the chemical reaction was complete, the system was weighed again.

The mass of the reactants is measured to be a total mass of 122.8 g.

After the reaction is complete, what will be the mass of products formed?

Record only your final answer with the correct number of significant digits and proper units.
