Approx....4.4*g........

Explanation:

There are (3.2*g)/(16.00*g*mol^-1)=0.20*mol WITH RESPECT TO OXYGEN atoms (note the distinction between oxygen atoms and oxygen molecules).

And THUS WITH RESPECT TO CARBON DIOXIDE we need a 0.10*mol quantity of carbon dioxide (in as much as each mole of carbon dioxide supplies 2 mol of oxygen atoms)....

And so 0.10*molxx44.01*g*mol^-1=4.40*g of carbon dioxide.....
