Answer: 8 moles

Step-by-step explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 Liters at STP and contains avogadro's number
6.023* 10^(23) of particles.

1 molecule of
Pb(SO_4)_2 contains = 8 oxygen atoms.

Thus
6.023* 10^(23) molecules of
Pb(SO_4)_2 contains =
(8)/(1)* 6.023* 10^(23)=48.2* 10^(23) atoms of Oxygen.

To calculate the moles, we use the equation:


\text{Number of moles}=\frac{\text{Given atoms}}{\text {Avogadro's number}}


\text{Number of moles}=\frac{48.2* 10^(23)}{6.023* 10^(23)=8moles

Thus 1 mole of
Pb(SO_4)_2 contains 8 moles of oxygen atoms.
