Answer:
Energy, 
Explanation:
It is given that,
Mass of matter, m = 1 g = 0.001 Kg
If this matter is completely converted into energy, we need to find the yield. The mass of an object can be converted to energy as :
c = speed of light
So, the energy yield will be 
. Hence, this is the required solution.
