The volume of the gas cylinder is 25.7 liters and exerts a pressure of 670 mmHg. If part of the gas is used, the pressure drops to 595 mmHg. What would be the remaining volume of gas? Show the work.

Respuesta :

Answer:

The remaining volume of gas is 28.939 L

Explanation:

Boyle's law:

assuming the constant temperature, the pressure of a gas varies inversely with the volume.

V1 * P1 = V2 * P2

∴ V1 = 25.7 L

∴ P1 = 670 mm Hg

∴ P2 = 595 mm Hg

∴ V2 : remaining volume of gas

⇒ V2 = ( V1 * P1 ) / P2

⇒ V2 = (  25.7 L * 670 mm Hg ) /  595 mm Hg

⇒ V2 = 28.939 L
