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.
An empirical conversion factor.
A mole.
1. 6.022 X 1023 is Avogadros number (Avogadros constant) the number of atoms in a mole.
No.
Its avogadros number
I asked this question wrong. It should be Avogadros Number. Sorry!
atoms in 12 g of c-12
Avogadros number (approximately). The atomic weight of iron is 55.845. Avogadros number , the number of atoms in a mole of an element, or the number of molecules in a mole of a compound is 6.023 X 1023
6.023*10^23
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.
