Franklin was performing an experiment by combining hydrochloric acid and sodium hydroxide. He measured the mass of his reactant materials to be 35g. The reaction resulted in the production of salt and water. He reported that his products weighed 32g.Which best describes the results of Franklin’s experiment?

The law of conservation of mass says that in a chemical reaction, the total mass of the reactants equals the total mass of the products. Franklin measured 35 g of reactants, so the salt and water together should also weigh 35 g. Since he reported only 32 g of products, an error occurred in the measurement or reporting.
