(a) Write 'true' or 'false' for each statement. (a) A mole of horses contain a mole of horse legs.

검증된 단계별 안내

Understand the concept of a mole: A mole is a unit in chemistry that represents \(6.022 \times 10^{23}\) entities, whether they are atoms, molecules, ions, or other particles.

Consider the statement: 'A mole of horses contain a mole of horse legs.'

Recognize that a horse typically has 4 legs.

If you have a mole of horses, you would have \(6.022 \times 10^{23}\) horses.

Therefore, a mole of horses would have 4 moles of horse legs, since each horse has 4 legs.

주요 개념

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 contains approximately 6.022 x 10^23 entities, such as atoms, molecules, or in this case, horses. This concept allows chemists to relate macroscopic quantities of substances to the number of particles they contain.

Stoichiometry

Stoichiometry is the area of chemistry that deals with the relationships between the quantities of reactants and products in chemical reactions. It is based on the conservation of mass and the mole concept, allowing for calculations involving the amounts of substances consumed and produced in a reaction. Understanding stoichiometry is essential for determining the number of legs in relation to the number of horses.

Animal Anatomy

Understanding the anatomy of horses is crucial for this question, as it provides insight into the number of legs a horse has. Each horse typically has four legs, which means that a mole of horses would contain four moles of horse legs. This biological knowledge is necessary to accurately interpret the relationship between the number of horses and their legs.
