Answer 2

i dont remeber,mass of particle =6,13*10^23..

Answer 3

There's Avogadro's constant:
6.02214129(27) × 10^23

Not 6.13 though.

Answer 4

6.02x10^23 is not a mass at all. It's the number of particles in a mole of a substance. So for instance 6.02x10^23 particles of H2O is 1 mole of water is about 18 grams of H2O. It shows how incredibly tiny molecules are.
