Problem

Each fission of a

^{235}\mathrm U

nucleus releases about

200\,\text{MeV}

of energy. Estimate the total decrease in mass when one mole of

^{235}\mathrm U

undergoes complete fission. (Take

1\,\text{u}=931\,\text{MeV}/c^2

N_A = 6.02\times10^{23}\,\text{mol}^{-1}

c=3.0\times10^{8}\,\text{m/s}

.) (a)

0.022\,\text{g}

(b)

2.2\,\text{g}

(c)

0.22\,\text{g}

(d)

22\,\text{g}
