Question

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

Answer 1

Moles of oxygen molecules produced = 3 mol

Step-by-step 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.
