"The laser light is directed on to a small volume of deuterium fuel. This fuel is confined for a short time by its own inertia. The temperature increases considerably and fusion occurs for a brief instant converting deuterium into an isotope of helium.
2(2,1H) ---> (3,2He) + (1,0n)
The masses of the reacting nuclei are:
2H-----> Mass/u = 2.01410
3He-----> Mass/u = 3.01603
1n------> Mass/u = 1.00867
1 u = 1.66*10^-27 Kg.
Show that the number of atoms of deuterium involved in the fusion process is about 10^9 if the energy yield is only 10 millionths of the energy delivered by the laser (the efficiency is equal to 10^-5)"
I calculated the binding energy by using, DE = c^2Dm and the answer is 5.11*10^-13 J (answer is correct for that) Not sure what to do next here cause i don't really understand it tbh. If someone could explain to me what to do in the next bit please.
Thanks in advance.
