If we assume that carbon monoxide (
#\mathbf(PV = nRT)# where:
#P# is the pressure of the gas. We can use#"bars"# as our units.#V# is the volume of the gas in#"L"# .#n# is the#\mathbf("mol")# s of gas.#R# is the universal gas constant,#"0.083145 L"cdot"bar/mol"cdot"K"# .#T# is the temperature of 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.
