<span>The number of bonded pairs of electrons in a covalent bond equals the bond order.
For example:
In molecule of hydrogen (H</span>₂), bond order is 1 (H-H), because there is one pair of electrons between hydrogen atoms.
In molecule of oxygen (O₂), bond order is 2 (O=O), because there are two pair of electrons (4 electrons) between oxygen atoms.
In molecule of nitrogen (N₂), bond order is 3 , because there are three pair of electrons (6 electrons) between nitrogen atoms.

Answer: 8.7 grams
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 
of particles.
To calculate the moles, we use the equation:
As oxygen is in excess, Aluminium is the limiting reagent and limits the formation of products.
According to stoichiometry:
4 moles of aluminium give = 2 moles of 
Thus 0.17 moles of aluminium give=
Mass of 
Thus the mass of is 8.7 grams
