Answer:
10.91 gm of oxygen would have reacted.
Explanation:
according to "law of conservation of mass", mass can neither be created nor be destroyed.
so, => amount of oxygen reacted = amount of carbon dioxide - amout of carbon.
=> 15.00 - 4.09 = 10.91 gm oxygen.
=> hence, we got the value. now just relax.
