Expert Answer:

One mole of carbon is burnt,
 
space space straight C subscript open parentheses straight s close parentheses end subscript space space plus space space straight O subscript 2 subscript open parentheses straight g close parentheses end subscript end subscript space rightwards arrow with space space space space space space on top space space CO subscript 2 subscript open parentheses straight g close parentheses end subscript end subscript space space
1 space mol space space space space space 1 space mol space space space space space space space space 1 space mol
12 space straight g space space space space space space space space 32 space straight g space space space space space space space space space 44 space straight g
 
That is 1 mole of carbong requires 32 gm of oxygen to produce 1 mole of CO2.
Here 16 gm of oxygen is given, so oxygen is the limiting agent.
 
32 gm of oxygen gives 1 mole of  CO2
Therefore, 16 of oxygen will give,
 
equals space fraction numerator 16 cross times 1 over denominator 32 end fraction

equals space 0.5 space mole space CO subscript 2

equals space 22 space gm space of space CO subscript 2 space
 
Therefore the amount of CO2 formed is 22 gm.
