atoms in 12 g of c-12
The unit is "per mole", or mol^-1.
A prime number has no factors except itself and 1.
If the conversion factor is exact, then the number of significant figures in the answer is the same as the number of significant figures in the original number.If the conversion factor is an approximation, then the number of significant figures in the result is the lesser of this number and the number of significant figures in the original number.
Incorrect. Square numbers are composite and have an odd number of factors.
An empirical conversion factor.
A mole.
No.
Its avogadros number
I asked this question wrong. It should be Avogadros Number. Sorry!

It is 6.02 (times) 10 to the power of 23
The unit is "per mole", or mol^-1.
It is the number of fundamental particles - atoms or molecules - of a substance in 1 mole of that substance.

There is 1 mole of atoms in 6.022 x 10^23 atoms of any element.
