Question

ball has a volume of 5.27 liters and is at a temperature of 27.0°C. A pressure gauge attached to the ball reads 0.25 atmosphere. The atmospheric pressure is 1.00 atmosphere.

Answer 1

The absolute pressure inside the ball is 1.25 atmospheres.

The ball contains 0.267 moles of air

Step-by-step explanation:

Answer 2

The absolute pressure inside the ball is 1.25atm.

Step-by-step explanation:

Given-

Volume, V = 5..27L

Temperature, T = 27°C

Gauge Pressure, Pg = 0.25 atm

Atmospheric pressure, Patm = 1 atm

Absolute pressure, Pabs = ?

We know,

Therefore, absolute pressure inside the ball is 1.25atm.
