Please I really really need help 1) What is Avogadro's number?
2) What is the relationship between Avogadro's number and Carbon atom?
3) What is unified atomic mass unit?
Don't answer the question for points if you don't know what it means, you will be reported
Thank you if you do :D

1) It is the number of particles in one mole of substance. It is an arbitrary definition to denote an amount of substance, not by its weight but by its number of molecules. Why? because that is convenient when doing certain calculations involving molecule formulas.

2) 1 mole of substance contains exactly as many particles as there are atoms  in 12 grams of carbon-12.

3) The unified atomic mass unit is 1/12 of the mass of 1 carbon-12 atom.

So you see all three concepts are linked together.
