In a closed system 11 grams and 14 grams of substances react completely. What will be the total product mass?

Answer and explanation

Correct answer: 25 grams

According to the law of conservation of mass, in a closed system the total mass of reactants before a reaction equals the total mass of products after the reaction. Therefore, total product mass = 11 g + 14 g = 25 g. The value 3 g is only the difference between the given masses, not the product mass. Exam tip: For a closed-system reaction, add the masses of all reactants to obtain the total mass of products.
