Number of atoms in a CNT

[Ankur Jha]

Hello friends.......
I wish to know how to calculate the number of atoms in a CNT. Also, does it depend on the (n,m) value ? If yes, please tell me the mathematical formula for the same.
If it depends on other factors, kindly mention them as well.

Seeking for a fruitful reply from the readers of this post as soon as possible......

Thank You

For this question, you can figure out the answer by yourself.

From the (n,m) values, you can know the area of the graphene sheet to be wrapped for the CNT. Since the area of the primitive unit cell of graphene can be easily calculated. The  division between these two area could give the number of atoms in the (n,m) CNT.
