Question

Energy equivalent of 1 amu is 931 MeV. If true enter 1, else enter 0.

Answer 1

`$1$ u $=1.66\times {10}^{-27}$ kg

$1$ eV $=1.602\times {10}^{-9}$ J

The energy equivalent to $1$ u of mass $=$ mc${}^2$

$=(1.66\times {10}^{-27})(2.998\times {10}^8)$

$=1.492\times {10}^{-10}$ J

$=(1.492\times {10}^{-10}/1.602\times {10}^{-19})$ eV

$=931\times {10}^6$ eV

$=931$ meV

Hence, the given statement is correct.
