chm100 if a reaction vessel contains 0 15 mol ko2 and 0 25 mol h2o how many moles of o2 can be produced which is the limiting reagent

4 KO2 (s) + 2 H2o (1) –> 4 KOH (s) + 3 O2 (g)

If a reaction vessel contains 0.15 mol KO2 and 0.25 mol H2o how many moles of O2 can be produced? Which is the limiting reagent?
