   88226Ra_{\ \ 88}^{226}Ra  ----->    86222Rn_{\ \ 86}^{222}Rn   +  24He_2^4He  
Given that the mass of     88226Ra_{\ \ 88}^{226}Ra   is 240.74 amu,    86222Rn_{\ \ 86}^{222}Rn   is 236.018 amu and  24He_2^4He   is 4.003 amu. Calculate the nuclear energy released.
[1 amu = 1.66 × 10–27 kg and speed of light in vacuum, c = 3.00 × 108 m s–1]

 _{\ \ 88}^{226}Ra  ----->  _{\ \ 86}^{222}Rn   +  _2^4He  
Diberi jisim   _{\ \ 88}^{226}Ra   ialah 240.74 amu, jisim _{\ \ 86}^{222}Rn   ialah 236.018 amu dan jisim  24He_2^4He   ialah 4.003 amu. Hitungkan tenaga nuklear yang dibebaskan. 
[1 u.j.a = 1.66 × 10–27 kg dan laju cahaya dalam vakum, c = 3.00 × 108 m s–1]

 1.30 × 1081-1.30\ \times\ 10^{-81} 

 1.07 × 10101.07\ \times\ 10^{-10}   J

 1.30 × 10811.30\ \times\ 10^{81}   J

 1.07 ×x 10101.07\ \times x\ 10^{10}   J
