Answer :
A helium-filled balloon has a volume of 4.50 L at a barometric pressure of 747.3 mmHg. Given the balloon’s volume is neither increasing nor decreasing, the pressure of the helium inside the balloon is 747.3 mmHg.
A helium-filled balloon has a volume of 4.50 L when the temperature is 22.5 degrees C and the barometric pressure is 747.3 mmHg.
What is barometric pressure?
Barometric pressure is the measurement of air pressure in the atmosphere, specifically the measurement of the weight exerted by air molecules at a given point on Earth.
What is the pressure of the helium gas?
The pressure of the helium gas is the force that the gas exerts on the container boundaries, in this case, the balloon.
We know that the balloon’s volume is neither increasing nor decreasing. This means that the barometric pressure and the pressure of the helium gas are at equilibrium. That is, the pressure of the gas is 747.3 mmHg as well.
