The value of Avogadro's number is commonly written as?

Explanation:
Avogadro's number tells you how many elementary entities are in one mole of a substance. The commonly used value is 6.02×10^23 entities per mole (often written 6.02×10^23 mol^-1). The exact value is 6.02214076×10^23, but rounded to three significant figures that’s 6.02×10^23, which is sufficient for most calculations. The other options would correspond to having ten times, a hundred times, or a tenth of the correct number of particles in a mole, so they don’t match the standard definition.
