using Avagadro's number you can go from a number of something to mols, or you can go backwards, from mols of something to particles/atoms/molecules etc.
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.
A mole.
An empirical conversion factor.
Its avogadros number
No.
I asked this question wrong. It should be Avogadros Number. Sorry!
atoms in 12 g of c-12
The unit is "per mole", or mol^-1.
It is 6.02 (times) 10 to the power of 23
It is the number of fundamental particles - atoms or molecules - of a substance in 1 mole of that substance.
A prime number has no factors except itself and 1.

Because 16 is a square number and you wouldn't list the 4 twice.
