Well, clearly, water vapor is the least dense... And we cannot just claim that without data. Consider the following.
#rho_(H_2O(s)) = "0.9167 g/mL"# at#0^@ "C"# and#"1 atm"#
#rho_(H_2O(l)) = "0.9970749 g/mL"# at#25^@ "C"# and#"1 atm"#
#rho_(H_2O(g)) = "0.0005883 g/mL"# at#100^@ "C"# and#"1 atm"#
Gases are thus much less dense than their respective liquids. Usually about a thousand-fold...
