Which of the following is the value of Avogadro's number?

• A. 9.81 × 10^{5}
• B. 6.022 × 10^{23}
• C. 3.14 × 10^{8}
• D. 1.008 × 10^{2}

Answer: (B)

Verified step by step guidance

1. Understand that Avogadro's number is a fundamental constant in chemistry representing the number of particles (atoms, molecules, or ions) in one mole of a substance.
2. Recall the standard value of Avogadro's number, which is approximately \$6.022 \times 10^{23}$ particles per mole.
3. Compare the given options to this known value to identify the correct one.
4. Note that the other options (\$9.81 \times 10^{5}\(, \)3.14 \times 10^{8}\(, and \)1.008 \times 10^{2}$) are significantly smaller and do not match the scale of Avogadro's number.
5. Conclude that the correct value of Avogadro's number from the options provided is \$6.022 \times 10^{23}$.
