1 amu is equal to

Explanation

Acc. to Einstein.s mass energy equivalence,
`E = mc^`
`m = 1 a.m,u = 1 xx 1.66 xx 10^(-27) kg = 1.66 xx 10^(-27) kg `
`c = 3 xx 10^8 ms^(-1)`
`E = (1.66 xx 10^(-27))(3 xx 10^8)^2`
`= 1.66 xx 9 xx 10^(-27) +16 `
`= 14.9 xx10^(-11)`
` = 1.49 xx 10^(-10)`
`= (1.49 xx 10^(-10))/(1.6 xx 10^(-13)) MeV = 931.25 MeV `
`E ~~ 931 MeV `
`1 a.m.u. ~~ 931 MeV `
