How many moles of o2 are produced when 0.325 mol of ko2 reacts in this fashion?

Answer : The number of moles of produced are 0.244 moles.

Explanation :  Given,

Moles of = 0.325 moles

The balanced chemical equation follows:

By Stoichiometry of the reaction:

As, 4 moles of react to give 3 moles of

So, 0.325 moles of react to give moles of

Therefore, the number of moles of produced are 0.244 moles.
