A sample of oxygen gas occupies a volume of 250 mL at 740 torr pressure. What volume will it occupy at 900 torr pressure? (exact value up to 2 decimal points with correct unit) make sure to put single space between the number and unit (example: 40.6 torr)

Steam is stored inside an industrial vessel of 4.2 m³. After compression, the volume of steam reduces to 1.1 m³. Assume that the temperature was constant, find the initial pressure if the final pressure is 2.4 atm.

A sample of hydrogen at 1.65 atm had its pressure decreased to 0.454 atm producing a new volume of 755 mL. What was its original volume (V₁)?

At one sewage treatment plant, bacteria cultures produce 1000 L of methane gas per day at 1.0 atm pressure. What volume tank (V₂) would be needed to store one day’s amount of gas at a pressure of 5.0 atm?

• 200 L

• 200 mL

• 200,000 L

• 5,000 L

A balloon is transported from Baguio to Pangasinan. The volume and pressure of the balloon in Baguio is 2.2 L and 0.85 atm and the pressure in Pangasinan is 1.2 atm. Assuming the temperature to be constant, find the volume of the balloon in Pangasinan?

• 155 L

• 1.56 L

• 155,000 L

• 4 atm

Carbon dioxide is usually formed when gasoline is burned. If 30.0 L of CO₂ is produced at a temperature of 1.00 x 10³ °C and allowed to reach room temperature (25.0 °C) without any pressure changes, what is the new volume of the carbon dioxide?

A container holds 50.0 mL of nitrogen at 25° C and a pressure of 736 mm Hg. What will be its volume if the temperature increases by 35° C?

568 cm³ of chlorine at 25° C will occupy what volume at -25° C while the pressure remains constant?

A sample of helium has a volume of 521 cm³ at a pressure of 750 mm Hg and a temperature of 18° C. When the temperature is increased to 23° C, what is the volume of the helium?
