Express unified atomic mass unit in kg....

Express unified atomic mass unit in kg.

Text Solution

Verified by Experts

One atomic mass unit is the `(1)/(12)` of the mass of `""_(6)C^(12)` atom.
Mass of one mole of `""_(6)C^(12)` atom =12 g
Number of atoms in one mole = Avogadro.s number
`=-6.023xx10^(23)`
`:.` Mass of one `""_(6)C^(12)` atom =`(12)/(6.023xx10^(23))g`
`1 amu =(1)/(12)xx` mass of one `""_(6)C^(12)` atom
1 amu `=((1)/(12)xx(12)/(6.023xx10^(23)))`
`=1.68xx10^(-24) kg`
`=1.67xx10^(-27) kg`

Einstein's mass-energy relation emerging out of his famous theory of relativity relates mass (m) to energy (E) as E = mc^(2) where c is speed of light in vacuum. At the nuclear level, the magnitudes of energy are very small. The energy at nuclear level is usually measured in MeV, where I MeV = 1.6 xx 10^(-13)J the masses are measured in unified atomic mass unit (u) where, 1u = 1.67 xx 10^(-27) kg . (a) Show that the energy equivalent of luis 931.5 MeV. (b) A student writes the relation as lu = 931.5 MeV. The teacher points out that the relation is dimensionally incorrect. Write the correct relation.
