If there is a loss of 4.36 × 10-5 g of mass in a nuclear reaction, how much energy would be released? recall that c = 3 × 108 m/s. a. 1.45 × 10-13 kj b. 3.92 × 106 kj c. 3.92 × 109 kj d. 3.92 × 1012 kj

As E= mc²

E = (4.36 × 10^ -5) ×( 3 × 108 m/s.)²

E= 3.924×10^12J

E= (3.924×10^12)KJ/ 1000

E =3.92 × 109 kJ

Released energy,

Explanation:

It is given that,

Loss in mass in a nuclear reaction,

The relation between the mass and energy is given by Einstein mass energy equivalence equation :

c is the speed of light

So,

The energy released in a nuclear reaction is . Hence, the correct option is (B)
