The molar volume is the same for all gases. So the density depends only on the molar mass. Answer D) shows the gases in order of increasing molar mass, so they are also in order of increasing density.

We have STP , and we know that 1 mole of gas occupies V = 22.4 L = 0.0224... / m = 0.0224m³/mol / 0.0166kg/mol spec vol = 1.35 m³/kg at STP Hope this helps!

... by W = -nRT*ln(Vf / Vi) One mole at STP means Vi = 22.4 L so -1000 J = -1mol * 8.314J...
