Answer 2

Answer:

6.02 X 1023 atoms of oxygen.

Explanation:

Just as an amount of 12 is described by the term dozen, Avogadro's number is described by the term mole. A dozen eggs is 12 eggs; a mole of atoms is 6.02 X 1023 atoms. Avogadro's number can be used to count anything. You could have a mole of apples or a mole of Ping-Pong balls. You can get some idea of the magnitude of Avogadro's number by considering that a mole of Ping-Pong balls would cover the surface of the Earth with a layer approximately 60 miles thick. Avogadro's number is shown here to three significant figures, which is the degree of accuracy usually required in calculations. Actually, the number of items in a mole has been determined to six or more significant figures, the exact number depending on the method by which the number was determined.
