You are given that mass of ${ }_3^7 L=7.0160 u$,
Mass of ${ }_2^4 He =4.0026 u$
and Mass of ${ }_1^1 H =1.0079 u$
When 20 g of ${ }_3^7 Li$ is converted into ${ }_2^4 He$ by proton capture, the energy liberated, (in kWh ), is:
[Mass of nucleon $=1 GeV / c ^2$ ]
Mass of ${ }_2^4 He =4.0026 u$
and Mass of ${ }_1^1 H =1.0079 u$
When 20 g of ${ }_3^7 Li$ is converted into ${ }_2^4 He$ by proton capture, the energy liberated, (in kWh ), is:
[Mass of nucleon $=1 GeV / c ^2$ ]
- A$4.5 \times 10^5$
- B$8 \times 10^6$
- C$1.33 \times 10^6$
- D$6.82 \times 10^5$
