The amount of the mass in grams that was lost from the fusion reaction is 5.56×10¯⁷ Kg

Data obtained from the question

  • Energy (E) = 5×10¹⁰ J
  • Speed of light (c) = 3×10⁸ m/s
  • Mass (m) =?

How to determine the mass

Energy is defined as the ability to work.

The mass can be obtained as follow

E = mc²

Divide both side by c²

m = E / c²

m = 5×10¹⁰ / 3×10⁸

m = 5.56×10¯⁷ Kg
