How many moles of oxygen molecules can be produced from 6 moles of lead oxide

Moles of oxygen molecules produced = 3 mol

Explanation:

Given data:

Moles of oxygen molecules produced = ?

Number of moles of lead oxide decomposed = 6 mol

Solution:

Chemical equation:

2PbO₂          →        2PbO + O₂

Now we will compare the moles of oxygen and lead oxide.

                   PbO₂        :          O₂

                      2           :            1

                      6           :           1/2×6 =3 mol

three moles of oxygen molecules are produced.
