How does stoichiometry support the law of conservation of mass?


A It compares the mass of the reactants to the number of moles of reactants.

B It compares the mass of each reactant to the mass of each product.

C It compares the mass of the products to the number of atoms in the products.

D It compares the mass of the products to the mass of the reactants. ***

D) It compares the mass of the products to the mass of the reactants.
The law of conservation of mass states that the amount of mass must remain the same before AND after the chemical reaction. The reactants form the products through chemical reaction meaning that they both must have the same mass.

The stoichiometry supports the law of conservation of mass by comparing the mass of the products to the mass of the reactants.

What is stoichiometry?

Stoichiometry is the measurement of the reactant and product of a reaction.

It is found in the law of conservation of mass, which says that the mass of the reactant is equal to the mass of the product.

Due to stoichiometry, if the mass of the product is known then, the mass of the reactant can be known.

Thus, the correct option is D.
