Molar mass :
H₂O = 18.0 g/mol
O₂ = 32.0 g/mol
<span>2 C</span>₄<span>H</span>₁₀<span> + 13 O</span>₂<span> = 8 CO + 10 H</span>₂<span>O
</span>
13 x 32.0 g O₂ ------------- 10 x 18.0 g H₂O
? g O₂ ------------- 2.46 g H₂O
Mass O₂ = 2.46 x 13 x 32.0 / 10 x 18.0
Mass O₂ =1023.36 / 180
=> 5.68 g of O₂
hope this helps!

Explanation:
Oxygen has six electrons in its outermost shell. This means that its octet can be completed when it shares two electrons with another oxygen atom.
In a covalent bond, each bonding atom contributes one electron to the bond. This means that four electrons are shared between two oxygen atoms. Each atom contributes a total of two electrons which are shared. This molecule of oxygen satisfies the octet rule rather than a single atom of oxygen.
An image of the oxygen molecule is attached to this answer.
This system of two oxygen atoms joined together in a covalent bond is called an oxygen molecule(O2).
