What does the conversation of mass say about the amount of atoms in the reactants compared to the products?

the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction. If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system.

Explanation:

The Law of Conservation of Mass states that mass cannot be created or destroyed.

In a chemical reaction, this means the mass of the reactants (substances going in and being changed) must equal the mass of the products (new substances from the reaction).

In addition, the amount of atoms must stay the same. The atoms can and will reconfigure to form different compounds, but the number of atoms stays the same.

girl imma just put my comment here because i need a couple point okurrttt
