• A. 602,000,000,000,000,000,000,000
• B. 602,200,000,000,000,000,000,000
• C. 60,220,000,000,000,000,000,000
• D. 6,022,000,000,000,000,000,000

Answer: (D)

Verified step by step guidance

1. Understand that Avogadro's number is a constant used to represent the number of particles (atoms, molecules, ions, etc.) 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. Convert the scientific notation \$6.022 \times 10^{23}$ into standard decimal notation by moving the decimal point 23 places to the right.
4. Write out the number with commas separating every three digits for clarity, resulting in a number with 24 digits in total.
5. Compare the given options to the correctly written decimal form of Avogadro's number to identify the correct representation.
