Answer:

E = 2.7 × 10¹⁵ J

Step-by-step explanation:

Data provided:

Mass defect = 0.030 Kg

Now,

the relation between the mass defect and energy is given as:

E = mc²

where,

E is the energy

m is the mass

c is the speed of the light = 3 × 10⁸ m/s

On substituting the respective values in the above relation, we get

E = 0.030 × ( 3 × 10⁸ )²

or

E = 2.7 × 10¹⁵ J
