E is the energy
c is the speed of light $c\approx3 \times 10^{8}~m/s$
m is the mass.

In order to obtain the answer in joule you need to convert gram to kilogram as:
$$\large 1~J=1~\frac{ kg \times m^2 }{ s^2 }$$

I help you til you get the question correct.

All you got to do really, is to convert your 1 gram to kilogram and then plug into the equation using the speed of light I gave you.
