Answer:
Answer is b. Cannot see the attached image though.
Explanation:
<span> 2 moles of N2O5 = 4 moles of NO2
2.4 mol N2O5/1 X 4 mol NO2/2 mol N2O5 (this way you can cross out the N2O5 mol and just be left with NO2 mol)
2.4 X 4 = 9.6
9.6/2 = 4.8
4.8 mol NO2 are formed</span>
The answer to the question is b
