If we assume that carbon monoxide (**ideal gas law**:

#\mathbf(PV = nRT)# where:

#P# is thepressureof the gas. We can use#"bars"# as our units.#V# is thevolumeof the gas in#"L"# .#n# is the#\mathbf("mol")# sof gas.#R# is theuniversal gas constant,#"0.083145 L"cdot"bar/mol"cdot"K"# .#T# is thetemperatureof the gas in#"K"# .

At STP,

#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.
