A sample of argon gas occupies a volume of 7.82 L at 50°C and 777 mm Hg. The volume of the gas sample increases to 8.84 L while its pressure decreases to 506 mm Hg. If the ideal gas law is obeyed, the temperature of the gas sample at the new volume and pressure is °C.

A sample of carbon dioxide gas at a pressure of 948 mm Hg and a temperature of 27°C, occupies a volume of 12.3 liters. If the gas is cooled at constant pressure to a temperature of 0.°C, the volume of the gas sample will be l L.

A 7.13 L cylinder contains 1.82 mol of gas A and 3.77 mol of gas B, at a temperature of 31.8 °C. Calculate the partial pressure of each gas in the cylinder. Assume ideal gas behavior. PA= PB = What is the total pressure? PTotal = kPa kPa kPa

A flask contains 740 mmHg of nitrogen (N2) gas in a 4.00 L container at 25.0 °C. If 44.0 g of carbon dioxide (CO2) gas is added to this flask at constant volume and temperature without any loss of the nitrogen already inside, what is the final pressure (in atm) of the container? Assume both gases behave as ideal gases. Given: 1 atm =760 mmHg Enter the numerical value (no units), using 3 significant figures. Type your answer...

A 44.0 L metal cylinder stores a sample of gas at 6 °C under 1.02 atm. The temperature of the storage unit rises to 76 °C, causing the gas to decompose and doubling the number of moles in the cylinder. Note: R = 0.08206 Latm/molK Determine the moles of gas in the cylinder before any decomposition occurs. Determine the pressure in the cylinder after the decomposition in atmospheres.

1. If the pressure remains constant, what volume will 25.6 L of a gas at 84°C occupy at standard temperature? 2. A flask containing 90.0 L of hydrogen was collected at 75°C. At what temperature would the volume be 70 L? 3. A gas is confined in a cylinder. The starting temperature of the cylinder is 760.0 K and the volume is 2L. If the cylinder is cooled, reducing the temperature to 450.0 K, what is the new volume? 4. If a gas occupies a volume of 7.33 L at 10°C, at what temperature, in °C, will it occupy a volume of 12.25 L if the pressure remains constant? 5. A gas occupies a volume of 5.60 L at a temperature of 120°C. To what temperature must the gas be lowered, if it is to occupy 4.00 L?

Entonox is an anaesthetic gas containing 50% oxygen and 50% nitrous oxide(N2O). If 200L of the gas mixture is compressed into a cylinder with a volume of 2.20L what is the total pressure in the cylinder, assuming the temperature remains unchanged?

A gas sample has a volume of 169 mL at 0.00 ∘C. The temperature is raised (at constant pressure) until the volume is 222 mL. What is the temperature of the gas sample in ∘C at this volume?

A reaction between liquid reactants takes place at 33.0 °C in a sealed, evacuated vessel with a measured volume of 20.0 L. Measurements show that the reaction produced 23. g of carbon monoxide gas. Calculate the pressure of carbon monoxide gas in the reaction vessel after the reaction. You may ignore the volume of the liquid reactants. Round your answ to 2 significant digits. pressure: ||| atm

A sample of helium gas occupies a volume of 8.64 L at 41.0°C and 0.960 atm. If it is desired to increase the volume of the gas sample to 11.2 L, while increasing its pressure to 1.23 atm, the temperature of the gas sample at the new volume and pressure must be °C.
