Q2

Calculate the energy released (in MeV) in the following fission reaction, given the atomic masses: 92235U+01n56141Ba+3692Kr+301n+Energy^{235}_{92}\text{U} + ^1_0\text{n} \rightarrow ^{141}_{56}\text{Ba} + ^{92}_{36}\text{Kr} + 3^1_0\text{n} + \text{Energy} Given atomic masses: Mass of 92235U=235.04393u^{235}_{92}\text{U} = 235.04393\,\text{u} Mass of 01n=1.00866u^1_0\text{n} = 1.00866\,\text{u} Mass of 56141Ba=140.91441u^{141}_{56}\text{Ba} = 140.91441\,\text{u} Mass of 3692Kr=91.92616u^{92}_{36}\text{Kr} = 91.92616\,\text{u} (Use 1u=931.5MeV/c21\,\text{u} = 931.5\,\text{MeV/c}^2)
