KWh to g/year?

A typical home uses approximately 1600 kWh of energy per month.If the energy came from a nuclear reaction, what mass would have to be converted to energy per year to meet the energy needs of the home? (in g/year)

I dont know how to do this problem :S

the things you need to know to solve the problem are:

a watt has units: J/s

E(in joules) [tex]= mc^{2}[/tex] <---this is the equation you should use to calculate how much mass is required to be converted.

[tex]c = 2.9979 x 10^{8}[/tex]m/s <---speed of light.
