The ratio of Pu238 and O2 in Plutonium dioxide??? Hello, guys. I was wondering if I can find a ratio of Pu238 and O2 in PuO2. In my problem set, these are all I have. - 238/94 Pu -----86yrs----> 4/2 He + 234/92 U + 5.59 Mev - 238PuO2 : 6000 gram in a sphere (10 cm diameter) - Density of PuO2 : 11.46 g/cc Q1) Calculate the number of curies of 238 Pu in this sphere Q2) Calculate the power generated by this sphere (watt) Since I couldn't find how much Pu or O2 is in PuO2 respectively, I couldn't simple figure the curies of Pu. Thus I've tried to find the ration for a couple of hours on the web but nothing came out. Does anyone help me out? Thanks, Ryan.
