Question

In the gaseous state, N₂O₄ partially dissociates to NO₂ in a reversible reaction. 24.0 grams of N₂O₄ is charged to a vessel and occupies a volume of 15,100 cm³ at 363K and 97.3 kPa. You can approximate the molecular weight of N as 14 g/mol and that of O as 16 g/mol.

Calculate the percent dissociation of N₂O₄ to NO₂ on a molar basis (what fraction of the initial moles of N₂O₄ dissociate toNO₂?)
