How do you do such a problem and what is the answer?

e=mc^2
4.2 x 10^6 = m x (299798458)^2
m=4.67 e-11 grams
In short, almost nothing

the subject with this simplistic analogy is that it quite is impossible to rigidity skill to offer count number. It occurs at very small scales, yet through fact of entropy, loose skill or skill in the form of sunshine or warmth is a lot lots greater in all risk than skill being compelled to be typical mass. The opposite technique, whether, is complete. Nuclear explosions are a results of the opposite technique, it is, mass changing into skill. that is going to be stated that no longer all the uranium/plutonium mass is annihilated in a reaction, so which you do no longer see explosions which might cripple the international ( that little 9x10^sixteen joules you have up there). purely a small quantity of the textile certainly annihilates. to comprehend purely how severe that is, purely open a e book and look on the mean life of a particle inclusive of a pion, which provides up the large majority of its mass whilst it decays into an electron/positron and photon.

No mass is converted into energy. All the energy of the explosion comes from chemical bonds. Mass was used to create those bonds, but once they are in place the mass remains constant, and so no mass can be lost. Were not talking about nuclear fission here.

1 tonne of TNT will release far more energy than this. 4.2E6 joules is only about 15 cents worth of electricity. But the mass equivalent of x joules is x/c^2 kg which is x/9E16 kg.

E = mc^2. Put 4.2 x10^6 J in for E and solve for m. (c = 3x10^8m/s^2).

m = 4.2*10^6/(3*10^8)^2
m = 4.6667*10^-2 micrograms

E=mc^2=4.2*10^6
m=4.2*10^6/10*10^16
=4.4*10^-11 (kg)
...........................................
1 ton = 1000 kg
