The correct Answer is:
To solve the matching question, we need to identify which of the given terms (A to E) corresponds to the description provided (1 to v). The specific description we are focusing on is "Its numerical value is 6.022 x 10^(23)". ### Step-by-Step Solution: 1. **Identify the Terms**: - A: mole - B: Avogadro's number - C: 22.4 L - D: vapor density - E: empirical formula 2. **Understand the Description**: - The description states, "Its numerical value is 6.022 x 10^(23)". This is a well-known constant in chemistry. 3. **Match the Description**: - The value "6.022 x 10^(23)" is known as Avogadro's number. It represents the number of particles (atoms, molecules, etc.) in one mole of a substance. - Therefore, we can conclude that the correct match for the description is: - **B: Avogadro's number** ### Final Answer: - The correct match is **B: Avogadro's number**.
