(b) How many bromine atoms are present in one mole of ¹²C?

검증된 단계별 안내

Understand the concept of a mole: A mole is a unit in chemistry that represents \(6.022 \times 10^{23}\) entities (Avogadro's number).

Identify the substance in question: The problem asks about bromine atoms in one mole of \(^{12}\text{C}\), which is carbon-12.

Recognize that carbon-12 does not contain bromine atoms: Carbon-12 is a pure element consisting only of carbon atoms.

Conclude that since carbon-12 does not contain bromine, there are zero bromine atoms in one mole of \(^{12}\text{C}\).

Reaffirm the understanding that the question is testing knowledge of chemical composition and the definition of a mole.

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Mole Concept

The mole is a fundamental unit in chemistry that quantifies the amount of substance. One mole of any substance contains Avogadro's number of entities, which is approximately 6.022 x 10²³. This concept allows chemists to convert between the mass of a substance and the number of atoms, molecules, or ions it contains.

Atomic Composition

Atomic composition refers to the types and numbers of atoms that make up a molecule or compound. In the case of bromine, it is a diatomic molecule (Br₂) in its elemental form, meaning each molecule consists of two bromine atoms. Understanding atomic composition is crucial for determining the number of atoms in a given quantity of a substance.

Chemical Symbols and Formulas

Chemical symbols and formulas are shorthand representations of elements and compounds. For example, 'Br' represents a bromine atom, while 'Br₂' indicates a molecule of bromine containing two bromine atoms. Recognizing these symbols is essential for interpreting chemical equations and understanding the relationships between different substances.
