The correct answer is: The total mass of the products would be 3.72 grams because mass cannot be gained or lost in the process.
According to the law of conservation of mass, the total mass of the reactants must equal the total mass of the products in a chemical reaction. In this case, 1.80 grams of sugar and 1.92 grams of oxygen gas are the reactants, giving a total mass of 3.72 grams. Therefore, the total mass of all products produced by the reaction will also equal 3.72 grams.
