The electrochemical cell described by the cell notation has a standard cell potential of 0.35 V. Calculate the Wmax (kJ) the cell has done if 1893.5 g of MnO42(aq) (Molar Mass  118.94 g/mol) forms. Round your answer to 3 significant figures.
Pt(s)  Hg22+(aq), Hg2+(aq)MnO4(aq), MnO42(aq)  Pt(s)
do i only need to use G=nFE to get W max or there is more to do

because it gives 1893.5g, it threw me off. I wasn't sure if it was there to trick me
