Answer:
source : Tes
1 gram atom = N – atoms = 6.023 x 1023 atoms = gram atomic weight
gram atomic weight = weight of N atoms in grams
1 gram molecule = N- molecules = 6.023 x 1023 molecules = gram molecular wt.
gram molecular wt. = wt. of N molecules in gram
number of moles of molecules ‘n’ = wt. (gram)/ molecular wt.= w/ m
number of moles of atoms ‘n’ = wt. (gram)/ atomic wt.
no. of moles ‘n’ = no. of particles / ( 6.023 x 1023)
