thank you for the help

1. The problem statement, all variables and given/known data

The total thermal power generated in a nuclear power reactor is 1.5 GW.

How much uranium-235 does it consume in a year?

ANSWER

m(^{235}U)=-----kg

2. Relevant equations

E=mc^{2}

3. The attempt at a solution

E=mc^{2}

1.5*10^{9}J*60sec*60min*24hr*365days=m*(3*10^{8}m/s)^{2}

Solving for m leaves me with .53 kg which come up incorrect in Mastering Physics.
