For the reaction N₂(g) + 3 H₂(g) → 2 NH₃(g) which of the following can be determined using only the coefficients of the balanced chemical equation?

Question

Quizplus · Accepted Answer

Only the number of moles of reactants and products can be determined using the coefficients of a balanced chemical equation. The weight of the products or reactants cannot be determined without additional information, such as molar masses or densities. Therefore, choice B is incorrect. Choice C is also incorrect as both options cannot be determined from the coefficients alone. Therefore, the best choice is A. We can use the stoichiometry provided by the coefficients to determine the number of moles of NH₃ produced when 4.2 mol of N₂ is consumed.
