Question

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

Answer 1

The answer to the question is Eight

Answer 2

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}}`

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