Answer:
0.207x10^16 Joules!
Explanation:
Using Einstein's law of mass energy, we know that the energy of a matter is:
E = mc^2
where, m [kg] = mass
c [m/s] = speed of light
In this case:
m=23g = 0.023kg.
c = 3×10^8m/s (This is an aproximation)
Then:
E = mc^2 = (0.023kg)(3×10^8m/s)^2 = 0.207x10^16 Joules!
