A determination of the density of a gas or vapor can provide a quick estimate of its molar mass even though for practical work mass spectrometry is far more precise. The density of a gaseous compound was found to be 1.23 g L-1 at 330 K and 25.5 kPa. What is the molar mass of the compound?
If the initial concentration of N2O4 is 0.50 M, and no NO2 is initially present, what is the equilibrium concentration of N2O4? Kc = 0.0059 at 298 K N2O4 (g) 2NO2 (g)
with vapor pressures at room temperature of 88, 680, 155, respectively, in order of decreasing boiling points.
