Question

calculate the mass present in 3×10²³ atoms of 'na'​

Answer 1

Answer:

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)

Explanation:

it is okk

Answer 2

Explanation:

Answer:

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)
