## Homework Statement

a mass of 3.33x10^-28kg of uranium is converted into energy during nuclear fission (exploding) according to einstien's formula

E=mc^2

where energy is measured in joules (J), m is measured in kg and c = 3000000000m/s is the speed of light

## Homework Equations

show that the amount of energy released during fission is 2.997x10^-1 J

## The Attempt at a Solution

E = mc^2

= 28kg x (3x10^8ms^-1)^2

= 28kg x (3x10^8ms^-1)x(3x10^8ms^-1)

= 28kg (9x10^16m^2s^-2)

= 28 x (9x10^16)kg m^2s^-2

= 252 x 10^16 J

= 2,520,000,000,000,000

thats my attempt.. i know nothing about this stuff and i was trying to do this for a friend.. I am curious now what others come up with
