The mass defect in a nuclear fusion reaction is 0.3%. What amount of energy will be liberted in one kg fusion reaction.

Explanation

To find the amount of energy liberated in a nuclear fusion reaction with a mass defect of 0.3% for a 1 kg fusion reaction, we can follow these steps:

### Step 1: Calculate the mass defect (Δm)
The mass defect is given as 0.3% of the total mass involved in the reaction. For a 1 kg fusion reaction, we can calculate Δm as follows:

\[ \Delta m = \frac{0.3}{100} \times 1 \text{ kg} = 0.003 \text{ kg} \]
