Problem

During one fission event of

^{235}_{92}\text{U}

by a thermal neutron, the products are

^{141}_{56}\text{Ba}

^{92}_{36}\text{Kr}

and three neutrons. Use the following atomic masses:

^{235}_{92}\text{U} = 235.043929\,\text{u}

, neutron

n = 1.008665\,\text{u}

^{141}_{56}\text{Ba} = 140.914411\,\text{u}

^{92}_{36}\text{Kr} = 91.926156\,\text{u}

. Calculate the percentage of the initial mass that is converted into energy in this single fission reaction. (Give the answer to two significant figures.)
