Question

When dinitrogen pentoxide (N2O5) decomposes to nitrogen dioxide and oxygen.Find volume of NO2 and O2 gases produced when a sample 54g of N2O5 is heated

Answer 1

Given info : When dinitrogen pentoxide (N2O5) decomposes to nitrogen dioxide and oxygen.

To find : the volume of NO₂ and O₂ gases produced when a sample 54g of N₂O₅ is heated.

Solution : 2N₂O₅ ⇒4NO₂ + O₂

Here two moles of N₂O₅ decomposes into 4 moles of NO₂ and one mole of O₂.

mass of N₂O₅ = 54g

Molecular mass of N₂O₅ = 28 + 80 = 108g

⇒no of moles of N₂O₅ = 54/108 = 0.5

so, 4 × 0.5 = 2 moles of NO₂ and 0.5 mole of O₂ are produced.

mass of NO₂ = 2 × 46 = 92 g

Mass of O₂ = 0.5 × 32= 16g

Therefore the masses of nitrogen dioxide and oxygen are 92g and 16 g respectively.

Answer 2

Answer:

When dintrogen pentaoxide (N2O5) a white solid is Heated, it decomposes to nitrogen dioxide and oxygen, find volume of No2 and o2 gases produced at STP when a sample of 54g of N2O5 is heated
