Question

in a nuclear plant, 1 * 10 ^27 J of energy is available from mass conversion How much mass was lost ?

Answer 1

`1.2* 10^(10)\ kg`

Step-by-step explanation:

Given that,

The energy of the nuclear plant,
`E=10^(27)\ J`

We need to find how much mass wast lost.

The relation between energy and mass is given by :

`E=mc^2`

Where

c is speed of light

`m=(E)/(c^2)\\\\m=(10^(27))/((3* 10^8)^2)\\\\m=1.2* 10^(10)\ kg`

So,
`1.2* 10^(10)\ kg` of mass was lost.
