4.4 g of CO_2 at STP has a volume of 2.2 L.

Explanation:

First, you start off with your given 4.4 g of CO_2. You convert it into moles using the Periodic Table. This may vary according to the atomic mass numbers on your Periodic Table.

On my version of the Periodic Table, 1 mol of Carbon has a mass of 12.0111 g and 1 mol of Oxygen has a mass of 15.9994 grams.

So 1 mol of CO_2 is 12.0111 * (15.9994 * 2) = 44.0099 g.

4.4 /44.0099 gives you 0.10 mol (2 significant figures).

1 mol of any gas will be equal to 22.4 L at STP. So 0.10 mol CO_2 * 22.4 L = 2.2 L of CO_2 at STP. (2 significant figures)
