Question

A ball has a volume of 5.27 liters and is at a temperature of 27.0C. A pressure gauge attached to the ball reads 0.25 atmosphere. The atmospheric pressure is 1.00 atmosphere. Calculate the absolute pressure inside he ball and the amount of air it contains

Answer 1

The absolute pressure inside the ball is

1.25

atmospheres.

The ball contains

0.267

mole of air.

Step-by-step explanation:

The absolute pressure is the sum of the gauge pressure and the atmospheric pressure.

The ball has an absolute pressure of 1.25 atmospheres:

0.25 atm + 1.00 atm = 1.25 atm.
