Calculate the amount of heat released (in kilojoules) by dumping 0.056 mole of radioactive $_{ 55 }^{ 137 }{ Cs }$ into the environment, when the total amount of energy released is ${ -1.54\times 10 }^{ -13 }J$.

Hint: 1 mole of Cs = ${ 6.023\times 10 }^{ 23 } \ \text{atoms}$

A

${ -1.54\times 10 }^{ -10 }kJ$

B

${ -5.194\times 10 }^{ 6 }kJ$

C

${ -8.624\times 10 }^{ -15 }kJ$

D

${ -9.275\times 10 }^{ 10 }kJ$
