Given that Avogadro's number is 6.02 X 1023. Calculate the number of molecules present in 100.0moles of
Nitrogen gas -N2 (g).

6.02 x 10^25

Explanation:

In order to find the number of molecules you simply multiply the number of moles by 6.022 x 10^23.

1 mole is always equal to 6.022 x 10^23 no matter what element.

100.0 x 6.022 x 10^23 = 6.02 x 10^25

The answer only has three significant figures because 100.0 only has three.
