    Finally!!!!!!!!!!!!!!!!!!!! i did it! the volume of the arena is: [50*(365/2)*(365/2)*4pi/3]/2 .... then get it to liters cause it is in cubic meters...for total moles divide by 0.082*273 ... for oxygen moles: multiply by 21% and then by the abundance of each isotope....for the answer multiply by the molecular weight (around 34) and that should be it....I don't know why but is sounds easier than it is...there are so many ways you can just fail in this question...

    So you do moles of O2 * (abundance O17 * abundance O18)?

    Also, what is the "mass" you mention?
