Illustrate: Understanding Avogadro's Constant

What is Avogadro's constant and how is it usually expressed?

Avogadro's constant is a factor used to determine the number of particles in a given substance. In scientific notation, how is Avogadro's constant expressed?

What is the standard form of Avogadro's constant?

In standard form, what is the equivalent numerical value of Avogadro's constant?

Final answer:

The Avogadro constant in standard form is 602,214,076,000,000,000,000,000, a number that represents the amount of particles in a mole and is usually expressed in scientific notation to manage its enormous size.

Explanation:

The Avogadro constant is a huge number that indicates the number of particles, like atoms or molecules, in one mole of a substance. When written out in standard form, it is 6.022 x 10²³, which is 602,214,076,000,000,000,000,000. This is because scientific notation is a method used to express very large or very small numbers in a more compact form. To write the Avogadro constant in standard form, you would move the decimal place to the right 23 times, giving you a number with 23 zeros after the initial digits.
