Problem

During a single fission event of a

^{235}\text{U}

nucleus, the mass defect is

0.20\,\text{u}

. If the total initial mass of the reacting system (uranium nucleus plus one neutron) is

236\,\text{u}

, calculate the percentage of the initial mass that is converted into energy. (Use

1\,\text{u}=1.66\times10^{-27}\,\text{kg}

; the numerical value of

1\,\text{u}

is not needed for the percentage.) a)
