The mass of a chemical equal to its molecular weight in grams,containing 6.023 x 10²³ molecules is a(n)

Question

Quizplus · Accepted Answer

The concept of a mole is defined as the amount of a substance that contains the same number of entities (such as atoms or molecules) as there are in 12 grams of carbon-12, which is approximately 6.023 x 10^23 entities. Therefore, if a substance contains 6.023 x 10^23 molecules (or atoms, or ions), its mass in grams is equal to its molecular (or atomic, or formula) weight. Thus, the given mass is equal to one mole of the chemical in question, and the correct answer is C: mole.
