You are given that mass of

{}^7_3\text{Li} = 7.0160 \text{ u}

, Mass of

{}^4_2\text{He} = 4.0026 \text{ u}

and Mass of

{}^1_1\text{H} = 1.0079 \text{ u}

. When 20 g of

{}^7_3\text{Li}

is converted into

{}^4_2\text{He}

by proton capture, the energy liberated, (in kWh), is : (1)

4.5 \times 10^5

(2)

8 \times 10^6

(3)

6.82 \times 10^5

(4)

1.33 \times 10^6
