Question

number of neucleons present in 0.2 of D20​

Answer 1

Answer:

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.
