Question

what is avogadro's number??

Answer 1

no of molucules in 1 mole of any element and it is given by \[6.023*10^{23}\]

Answer 2

what is meant by 1 mole?

Answer 3

"mole" is a word that refers to a specific number (6.023∗10^23), like "dozen" means 12

Answer 4

why this no?? (6.023∗10^23)?

Answer 5

good question. It is the perfect number of particles to make amu and grams comparable. one proton weighs about 1 amu, 1 mole of protons weighs 1 gram. this only works if a mole is 6.02 x 10^23

Answer 6

i see.
is that the only reason?

Answer 7

pretty much, it was named after avogadro, deduced by Perrin. It is a constant, lots of constants in chem and physics
