The combustion of propane may be described by the chemical equation,
C3H8(g) + 5O2(g) --> 3CO2(g) + 4H2O(g)
How many grams of O2(g) are needed to completely burn 97.3 g of C3H8(g)?

When heated, KClO3 decomposes into KCl and O2.
2KClO3 ---> 2KCl +302
If this reaction produced 74.6 g of KCl, how much O2 was produced (in grams)?
