The loss of mass in nuclear fusion is 0.02 g per mole of fuel. The molecular weight of the fuel is 5 g/mole. The amount of energy produced by consuming 1 kg of fuel in nuclear fusion is kWh.

The amount of energy produced by consuming 1 kg of fuel in nuclear fusion is kWh.

Explanation:

Mass of fuel = 1 kg = 1000 g

Moles of fuel =

The loss of mass in nuclear fusion is 0.02 g per mole of fuel

Loss of mass in nuclear fusion by consuming 200 mole : m

1 g = 0.001 kg

Energy produced during this process can be determined by mass energy equation :

The amount of energy produced by consuming 1 kg of fuel in nuclear fusion is kWh.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
