Characterize EACH of the three given statements as being TRUE or FALSE and then indicate the collective true-false status of the statements using the choices: (1) The molar mass of an element, in the solid state, has the same numerical value as the element's atomic mass.
(2) In a balanced chemical equation, the number of reactants must equal the number of products.
(3) One mole of N₂O₄ contains six moles of atoms.

Question

Quizplus · Accepted Answer

(1) False. The molar mass of an element in the solid state is the mass of one mole of the element's atoms, while the atomic mass is the average mass of one atom of the element. These values are not necessarily the same.(2) True. In a balanced chemical equation, the number of atoms of each element on the reactants' side must equal the number of atoms of that element on the products' side.(3) True. One mole of N₂O₄ contains two moles of N atoms and four moles of O atoms, for a total of six moles of atoms.
