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^-1222*g*mol^-1 is confined in a 22.4*L22.4*L container. What is the density of the gas in g*L^-1g*L^-1?
