Step by Step Solution

Step 1. Given information

The number is 6.02×1023.

Step 2. Calculation 

To write the Avogadro’s number in standard form shift the decimal 23 places towards the right from its current position.

Therefore,

6.02×1023=6×02×1000×1000×1000×1000×1000×1000×1000×100=602,000,000,000,000,000,000,000

Thus, standard form of Avogadro’s number is 602,000,000,000,000,000,000,000.
