Find the volume of NO2 and O2 gases produced at STP when a sample of 5

1.	Find the volume of NO2 and O2 gases produced at STP when a sample of 54g of N2O5 is heated
Answer» Dear Student, The BALANCE equation for the decomposition of N2O5 can be written as: 2 N2O5(g) → 4 NO2(g) + O2(g) Given: MASS of O2(g) formed = 1.60 g Molar mass of O2 = 16.0 g/mol Moles of O2 = Mass / Molar mass = 1.60 / 16.0 = 0.1 moles The mole ratio of O2 and NO2 is 1 : 4 hence moles of NO2 = 0.1 x 4 = 0.4 moles of NO2 Molar mass of NO2 = 46.00 g/mol Mass of NO2 = 46.00 x 0.4 = 18.4 g Answer: 18.4 g of NO2 will form..

Answer»

2 N2O5(g) → 4 NO2(g) + O2(g)

Given:

MASS of O2(g) formed = 1.60 g

Molar mass of O2 = 16.0 g/mol

Moles of O2 = Mass / Molar mass = 1.60 / 16.0 = 0.1 moles

The mole ratio of O2 and NO2 is 1 : 4 hence moles of NO2 = 0.1 x 4 = 0.4 moles of NO2

Molar mass of NO2 = 46.00 g/mol

Mass of NO2 = 46.00 x 0.4 = 18.4 g
