as per the mole relation
N/Na = 22.4/vol(litre)
N= 22.4 × 6.023×10²³ / 0.054
N = 2498.42 × 10²³
in 54 ml of H2O 2498.42 × 10²³ atoms are there from which the number of H atoms is 2/3
N of Hydrogen atoms = 2/3 × 2498.42 × 10²³
= 1665.61 × 10²³ atoms

yor anser is wrong
as moles of gas= 5.6/22.4
so it gives o.25 moles now we know molar m= 20/.25=80gm
no moles of all gases are not constant
and mole = 22.4 / vol in litres
which is also equal to w/ mass
which also equal.to N/ Na
we know Na and vol...
so i think my answer is right
