    I've been stuck on silver for some time now... PLEASE HELP. I tried using the mass difference between helium and oxygen for the equation e=mc2 and it didnt work then i tried calculating the binding energy for helium, multiplied it by four, the subtracted from that of oxygen but still nothing... i also tried dividing the answer by a mole of helium in grams to get it to joules/mol, still nothing. Please help.
