The larges mols OF ATOMS wins. moles = grams/atomic mass. For Pb that is 100 g/207.whatever = ? Be careful with O2. That is a MOLECULE so after you find the moles of the MOLECULE O2 you must multiply by 2 to get the number of ATOMS. answered by DrBob222 December 19, 2021 good advice on the O2, but since a million is so much less than 6.02E23, you can ignore it from the get-go. The others are in grams or moles, so they are at least in the same ball park. answered by oobleck December 19, 2021 @oobleck-----but I always do things the hard way.
