How many moles of N2O5 are produces by reacting 10 moles of O2?

4 moles of N₂O₅

Explanation:

Given parameters:

Number of moles of O₂  = 10moles

Unknown:

Number of moles of N₂O₅ produced  = ?

Solution:

To solve this problem, we must write the reaction equation first,

            2N₂  + 5O₂  →  2N₂O₅

IN the reaction above;

       5 moles of O₂ will produce 2 moles of N₂O₅;

       10 mole of O₂ will produce     = 4 moles of N₂O₅
