Question

How many moles of oxygen are in 1 mole of Pb(SO4)2

Answer 1

Answer: 8 moles

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 Liters at STP and contains avogadro's number $6.023\times 10^{23}$ of particles.

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

Thus $6.023\times 10^{23}$ molecules of $Pb(SO_4)_2$ contains = $\frac{8}{1}\times 6.023\times 10^{23}=48.2\times 10^{23}$ atoms of Oxygen.

To calculate the moles, we use the equation:

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

$\text{Number of moles}=\frac{48.2\times 10^{23}}{6.023\times 10^{23}=8moles$  

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