How to calculate the percentage difference between the mass of the reactants and the mass of the product relative to the mass of reactants?

The law of the conservation of mass states that in a closed system (totally closed to mass and energy), mass is neither created nor destroyed during a chemical reaction. We then expect that the total mass of the products should equal the total mass of the reactants. However, most chemical reactions performed in a typical school laboratory will not take place in a closed system.

To calculate the percentage difference between the mass of the reactants and the mass of the product relative to the mass of reactants, do the following:

% difference = ##”mass of reactants – mass of products”/”mass of reactants”## x 100
