At #"STP"#, one mole of ideal gas occupies occupies a volume of #22.4*L#. So.......

#rho, "density"="Mass"/"Volume"#.

If we assume that the gas behaves ideally (a safe assumption!) then,

#rho=(222*g*mol^-1)/(22.4*L*mol^-1)~=10*g*L^-1#.

A molar volume of gas whose mass is #222*g*mol^-1# is confined in a #22.4*L# container. What is the density of the gas in #g*L^-1#?
