Answer:
[tex]E = 13.428 \times 10^{46} J[/tex]
Explanation:
Mass of the Sun = [tex]1.989 \times 10^{30} Kg[/tex]
Amount of Hydrogen = 75% of Mass of Sun,
thus mass of Hydrogen (m) in the Sun is,
[tex]m = 1.989 \times 10^{30} \times \frac{75}{100}[/tex]
m = [tex]1.492 \times 10^{30}[/tex]
Speed of Light (c) = [tex]3 \times 10^{8} m/s[/tex]
Thus, energy(E) produced if whole of hydrogen is converted into energy,
E = mc²
[tex]E = 1.492 \times 10^{30} \times (3 \times 10^{8} )^{2}[/tex]
[tex]E = 1.492 \times 9 \times 10^{46}[/tex]
[tex]E = 13.428 \times 10^{46} J[/tex]
