Solution 17P
Here, we are going to calculate the number of moles of NO2 formed when the given amounts of N2O5 completely reacts.
Step 1:
The given chemical reaction is:
2N2O5(g) → 4NO2(g) + O2(g)
From the above equation, it is clear that, 2 moles of N2O5 reacts completely to give 4 moles of NO2 as product.
Therefore, 1 mole of N2O5 will give (4/2 = 2) mol of NO2 on complete reaction.
