It doesn't matter what the substance is.
All we need to know is the mass.
E = M C2
M = 8 kg
C = 3 x 108 m/s
C2 = 9 x 1016
E = M C2 = (8) (9 x 1016) = 7.2 x 1017 joules
In order to put this number into some kind of perspective . . .
The largest nuclear power generating plant in the US is the Palo Verde plant in Arizona.
It has three reactors, with generating capacities of 1313, 1270, and 1317 Megawatts.
With all three Palo Verde reactors operating simultaneously at 100% capacity, they would
generate power at the rate of (1313 + 1270 + 1317) = 3900 megawatts = 3.9 X 109 watts.
The energy equivalent of our 8 kg of mass, calculated above, compares to 100% of the
total Palo Verde rated capacity running for
(7.2 x 1017 joules) / (3.9 x 109 joules per second) =1.8462 x 108 seconds = about 70 months !
