One mole of particles of any substance contains how many particles?

• A. 3.01 × 10^{23}
• B. 6.022 × 10^{23}
• C. 1.00 × 10^{6}
• D. 6.022 × 10^{22}

Answer: (B)

Verified step by step guidance

1. Understand that the question is asking about the number of particles in one mole of any substance, which is a fundamental concept in chemistry related to the mole unit.
2. Recall that one mole is defined as the amount of substance that contains exactly \$6.022 \times 10^{23}$ elementary entities (particles), such as atoms, molecules, or ions. This number is known as Avogadro's number.
3. Recognize that the other numbers given (e.g., \$3.01 \times 10^{23}\(, \)1.00 \times 10^{6}\(, and \)6.022 \times 10^{22}$) are incorrect values for the number of particles in one mole.
4. Therefore, the correct answer corresponds to Avogadro's number, which is \$6.022 \times 10^{23}$ particles per mole.
5. This concept is essential because it allows chemists to count particles by weighing macroscopic amounts of material, linking the microscopic scale to the macroscopic scale.
