D
6,022,000,000,000,000,000,000
Verified step by step guidance1
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.
Recall the standard value of Avogadro's number, which is approximately \(6.022 \times 10^{23}\) particles per mole.
Convert the scientific notation \(6.022 \times 10^{23}\) into standard decimal notation by moving the decimal point 23 places to the right.
Write out the number with commas separating every three digits for clarity, resulting in a number with 24 digits in total.
Compare the given options to the correctly written decimal form of Avogadro's number to identify the correct representation.
