When CO2(g) is put in a sealed container at 730 K and a pressure of 10.0 atm and is heated to 1420 K, the pressure rises to 24.1 atm. Some of the CO2 decomposes to CO and O2.
Calculate the mole percent of CO2 that decomposes. Express your answer using two significant figures.
CO2 -------CO + 1/2O2
If 1mole of CO2 reacted then x moles reacted forming x moles of CO and 0.5x moles of O2
Mass = 49.8 g
Molaar mass of oxygen gas = 32 formula for the calculation of moles is shown below:
Presure and volume are constant, we can use the Avogadro's law as:-
V₂ is twice the volume of V₁
V₂ = 2VV₂=2V
n₁ = ?
n₂ = 1.55625 mol
Using above equation as:
oles of carbon dioxide = 0.778125 moles
Molar mass of = 44.0 g/mol
Mass of = Moles × Molar mass = 0.778125 × 44.0 g = 34.2 g
