A sample of helium gas is placed in a rigid cylinder that has a movable piston. The volume of the gas is varied by moving the pi
ston, while the temperature is held constant at 273 K. The volumes and corresponding pressures for three trials are measured and recorded in the data table below. For each of these trials, the product of pressure and volume is also calculated and recorded. For a fourth trial, only the volume is recorded.
State evidence found in the data table that allows the product of pressure and volume for the fourth trial to be predicted.

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 = mole
Volume of water vapor = 89 litres
Therefore,
Number of moles in 89 litres = ≈ 4 moles
