In a closed vessel total reactants are 68 grams. If one product is 41 grams what is the other product?

Answer and explanation

Correct answer: 27 grams

According to the law of conservation of mass, in a closed vessel the total mass of reactants equals the total mass of products. Therefore, mass of the second product = 68 - 41 = 27 grams. 68 grams is the combined mass of all products, not the mass of the other product alone. Exam tip: equate total reactant and product masses, then subtract the known mass.
