Calculate the energy equivalent of 1 atomic mass unit.

Text Solution

Verified by Experts

We take, m = 1 amu = `1.66 xx 10^(-27)` kg
`c = 3 xx 10^(8) ms^(-1)`
Then, `E = mc^(2) = 1.66 xx 10^(-27) xx(3 xx (10)^(8))^(2)`J
` = (1.66 xx 10^(-27) xx(3 xx10^(8))^(2))/(1.6 xx 10^(-19)) eV`
`E approx 981` MeV
`therefore` 1 amu = 931 MeV
