I've read a lot about the mole , avogadro's no. , molecular mass and such , but I can't seem to understand anything , and no , the wiki article wasn't helpful at all ! Put simply :
1- I read that the mole is the molecular mass expressed in grams , for example an Oxygen atom has 16 as a mass no and 8 as an atomic no. , does that mean that 1 mole of an oxygen atom is equivalent to 16 gms ? And since the oxygen molecule has 2 atoms then does that mean that one mole of it contains "2*16" moles ?
2- What is the difference between the mass of one mole and the molecular mass ?
3- what does avogadro's number have to do with all of this ? (please answer me soon , thank you in advance)
