Question

How many moles of NO₂ would be produced from 3.9 mol of O₂ in the reaction below assuming the reaction has a 57.0% yield?
2 NO (g) + O₂ (g) → 2 NO₂ (g)

Answer 1

The number of moles of NO₂ that would be produced from 3.9 mol of O₂ in the reaction is 5.13 moles NO2.

What is nitrogen?

Nitrogen is a monatomic gas. It is the most abundant gas present in the environment.

4.5 mol O2 x (2 mol NO2/ 1 mol O2) = 9 mol NO2

For 57% yield of the reaction

9 mol NO2 x 0.57 = 5.13 moles NO2.

Thus, the number of moles of NO₂ is 5.13 moles.
