The masses of neutron, proton and deuteron in amu are 1.00893,1.00813 and 2.01473 respectively .The packing of the deuteron in amu is

A

`11.65 xx 10^(-4)`

B

`23.5xx 10^(-4)`

C

`33.5 xx 10^(-4)`

D

`47.15 xx 10^(-4)`

Text Solution

Verified by Experts

The correct Answer is:
A
Deuteron `(""_(1)H^(2))` - Mass number is 2
Packing Fraction =`Delta M/A`
Where,
`Delta m = (m_(n) + m_(p)) - m_(d)` `Delta m = 0.00233`
Packing fraction = `0.0023/2`
`= 11.65 xx 10^(-4)`
