Answer:

4 moles

Explanation:

A mole is equal to 6.02214076 × 1023 of any chemical unit (atoms, molecules, ions)

To find number of moles in 89 litres of water vapor use the following formula:

1 mole = 22.4 L

That is 1 L = $\frac{1}{24}$ mole

Volume of water vapor = 89 litres

Therefore,

Number of moles in 89 litres = $\frac{89}{24}=3.7$ ≈ 4 moles
