The energy that would be released if the mass was converted to energy is 9 * 10^-4 J
What is Einstein equation?
According to the Einstein equation, mass and energy can be interconverted. This is possible by the use of the equation E = mc^2
Where;
m = mass
c = speed of light
Hence;
E = 1 * 10^-20 Kg * (3 * 10^8 m/s)^2
E = 9 * 10^-4 J
