How many moles of p2o5 are formed from 3.4 moles of o2

The answer to your question is  1.36 moles of P₂O₅

Explanation:

Data

moles of P₂O₅ = ?

moles of O₂ = 3.4 moles

Balanced chemical reaction

                4P  +  5O₂  ⇒   2P₂O₅

To solve this problem use proportions and cross multiplication. Consider the coefficients of the molecules of the balanced equation.

                 5 moles of O₂ 2 moles of P₂O₅

                 3.4 moles of O₂  x

                           x = (3.4 x 2) / 5

-Simplification

                          x = 6.8 / 5

-Result

                          x = 1.36 moles of P₂O₅
