The fusion reaction

^2_1\text{H}+^3_1\text{H}\rightarrow ^4_2\text{He}+n

has the following atomic masses:

^2_1\text{H}=2.0141\,\text{u}

^3_1\text{H}=3.0160\,\text{u}

^4_2\text{He}=4.0026\,\text{u}

, and

n=1.0087\,\text{u}

. Find the percentage of the initial mass that is converted into energy in a single fusion event. a)
