$~~1.755 \ "L"$

At $"STP"$ , a gas will contain approximately a volume of $22.7 \ "L"$ . Click here for the explanation.

So here, we need to convert $3.4 \ "g"$ of carbon dioxide into moles.

Carbon dioxide has a molar mass of $44 \ "g/mol"$ . So here, there exist,

$(3.4color(red)cancelcolor(black)"g")/(44color(red)cancelcolor(black)"g""/mol")=0.0772727273 \ "mol"$

And so, the molar volume is:

$0.0772727273color(red)cancelcolor(black)"mol"*(22.7 \ "L")/(color(red)cancelcolor(black)"mol")=1.75409090971 \ "L"$

$~~1.755 \ "L"$
