woops. So it's actually

(200 gm/s) / 250 g

And

200/250 + 200/251 + 200/252 + 200/253 + 200/254 + 200/255 + 200/256 + 200/257 + 200/258 + 200/259

Oh wow, that's interesting--but also confusing. A photon doesn't have a mass but it does have an "effective" mass? Also, if E=mc^2 holds, then without a mass there's no energy..?
