We’re being asked to determine the ranking of gases according to density.
We will use the ideal gas equation :
Which is the correct ranking of the density of these gases at 1.0 atm and 298 K?
(a) CO < N2O < Cl2 < HF
(b) Cl2 < N2O < CO < HF
(c) all of these have the same density
(d) HF < CO < N2O < Cl2
(e) HF < CO < Cl 2 < N2O
