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) Six mole-to-mole relationships are obtainable from a balanced chemical equation involving two reactants and two products.
(2) The compound H₂O has a greater formula mass than does the compound NH₃.
(3) The atomic mass unit (amu) and the gram unit (g) are related to one another through Avogadro's number.

Question

Quizplus · Accepted Answer

(1) is true because a balanced chemical equation involving two reactants and two products will have three mole-to-mole relationships: reactant 1 to reactant 2, reactant 1 to product 1, and reactant 2 to product 2.(2) is true because the formula mass of H₂O is 18.015 amu, while the formula mass of NH₃ is 17.031 amu.(3) is true because 1 amu is defined as 1/12 of the mass of a carbon-12 atom, and 1 g is defined as the mass of 6.022 × 10²³ carbon-12 atoms (Avogadro's number).
