Problem

In a fusion reactor, the reaction

\mathrm{^2_1D+^3_1T\;\rightarrow\;^4_2He\;(+17.6\,MeV)}

occurs at a rate of

3.0\times10^{20}

reactions per second. Calculate the rate (in kg s

^{-1}

) at which mass is converted into energy. Take

1\,\text{eV}=1.6\times10^{-19}\,\text{J}

and

c = 3.0\times10^{8}\,\text{m s}^{-1}
