Course

#### Question

Calculate the energy released in joules when 5 g of a material is completely converted into energy doing a nuclear reaction.

#### Solution

The energy released in joules when 5 g (5/1000 kg ) of a material is completely converted into energy during a nuclear reaction is given by Einstein's equation as

E = mc2

= (5/1000) xx (3 xx 10^8)^2

= 4.5 × 1014 J

Is there an error in this question or solution?
