If we assume that carbon monoxide ( $CO$ $"CO"$ ) is an ideal gas, then we can use the ideal gas law:

$P V = n R T$ $\mathbf(PV = nRT)$

where:

$P$ $P$ is the pressure of the gas. We can use $bars$ $"bars"$ as our units.

$V$ $V$ is the volume of the gas in $L$ $"L"$ .

$n$ $n$ is the $mol$ $\mathbf("mol")$ s of gas.

$R$ $R$ is the universal gas constant, $0.083145 L \cdot bar/mol \cdot K$ $"0.083145 L"cdot"bar/mol"cdot"K"$ .

$T$ $T$ is the temperature of the gas in $K$ $"K"$ .

At STP, $T = 0^{\circ} C = 273.15 K$ $T = 0^@ "C" = "273.15 K"$ , and $P = 1 bar$ $P = "1 bar"$ . So, to get the volume, just solve for $V$ $V$ .

$V_{CO} = \frac{n R T}{P}$ $color(blue)(V_"CO") = (nRT)/P$

$= ((0.220 cancel("mol CO"))("0.083145 L"cdotcancel("bar")"/"cancel("mol")cdotcancel("K"))(273.15 cancel("K")))/(1 cancel"bar")$

$=$ $color(blue)("5.00 L")$ to 3 sig figs.
