There are twice as many oxygen atoms as carbon atoms in carbon dioxide, so 100.0 moles of carbon dioxide would contain 200.0 moles of oxygen atoms.

In diphosphorous pentoxide (P4O10), there are 10 oxygen atoms for every molecule. Therefore, in 5.00 moles of diphosphorous pentoxide, there would be 5.00 moles x 10 oxygen atoms = 50.0 moles of oxygen atoms.

Two moles of oxygen gas are needed to make 4 moles of water in the reaction: 2H2 + O2 -> 2H2O.

Since there are 8 oxygen atoms in each molecule of C8H11NO2, you would have 29.6 moles of oxygen in 3.7 moles of C8H11NO2.

There are 6 moles of oxygen atoms in 2 moles of potassium dichromate (K2Cr2O7). Each mole of K2Cr2O7 contains 7 oxygen atoms, so 2 moles would contain 14 oxygen atoms. The molar mass of oxygen is 16 g/mol, so there would be 224 grams of oxygen in 2 moles of K2Cr2O7.
