## Homework Statement

Another mode in which uranium 235 can undergo fission is U + n -> Te + Zr +n. Calculate the energy change when 1g of uranium 235 undergoes fission in this way. The masses are U=235.04u. n=1.0087u. Te=134.92u. Zr=99.92u.

## Homework Equations

## The Attempt at a Solution

The mass of the left side is 236.0487u

The mass of the right side is 235.8487u

delta M=-0.2u

E=mc^2

=-0.2u x 9x106 J/kg x(1.66x10^-27kg/u)

=-.2.988x10^-21J/u ? (Please help me with units here!)

E1g=-2.988x10^-21J/u x 1g

(Units have failed me here, please tell me where I went wrong...)
