In D2O,
First, let us consider Deuterium which has 2 nucleons namely one proton and one neutron.
Second, Oxygen has 16 nucleons which 8 each of protons and neutrons.
So 1 molecule of D2O has 20 nucleons in total.

Hence 1 mole of D2O (20 grams) has
"20 x Avogadro number of nucleons"
That is '20 x 6.023 x 10^23 nucleons'
in 20 grams of D2O.

So in 0.2 grams we will have
0.2 x 6.023 x 10^23 nucleons

= 1.2046 x 10^ 23 nucleons.

anaik: thank you so much
siril: You're welcome.
anaik: its been really helpful for me
siril: :) i'm happy
siril: sorry....the answer is wrong, i'm so sorry that i didn't check it.....i'll correct it here
siril: 1 mole has 20 x Avogadro number of nucleons.....
siril: number of moles = given mass/molar mass = 0.2/20 = 0.01
siril: so, 0.01 moles has 0.01 x 6.023 x 10^23 nucleons
which is 6.023 x 10^21 nucleons
siril: The only mistake is that....i forgot to calculate the moles and wrote 0.2 grams
siril: if u still have doubt, then please ask......
