12. Argon (Ar) and helium (He) are initially in separate compartments of a container at 25°C. The Ar in compartment A, which has a volume V₁ of 6.00 L, has a pressure of 2.00 bar. The He in compartment B of unknown volume V3 has a pressure of 5.00 bar. When the two compartments are connected and the gases allowed to mix, the total pressure of gas is 3.60 bar. Assume both gases behave ideally. (a Determine the volume of compartment B. (b) Determine the mole fraction of He in the mixture of gases.

For many purposes we can treat dimethyl ether C2H6O as an ideal gas at temperatures above its boiling point of −24.°C. Suppose the pressure on a 480.mL sample of dimethyl ether gas at 4.00°C is doubled. Is it possible to change the temperature of the dimethyl ether at the same time such that the volume of the gas doesn't change? If you answered yes, calculate the new temperature of the gas. Round your answer to the nearest °C.
A sample of hydrogen (H2) gas was collected over water at 60°C. If the total volume of gas collected was 71.8 mL and the atmospheric pressure was 1.02 bar, what mass (in g) of hydrogen gas was collected above the water? The vapour pressure of water at 60°C is 150 torr.
Using the ideal gas law (PV=nRT), calculate how many moles of air are in the lungs of an average person with total lung capacity of 3.2 L? The pressure is 23.9 psi and body temperature is 37∞C. (R= 0.0821 L atm/ mol K) (14.7 psi/1 atm) (K = ∞C + 273).
A mixture of He and CO2 is placed in a 7.5L flask at 22C. The partial pressure of the He is 2.2 atm and the partial pressure of the CO2 is 1.9 atm. What is the mole fraction of He?
A sample of an ideal gas at 1.00 atm and a volume of 1.67 L was placed in a weighted balloon and dropped into the ocean. As the sample descended, the water pressure compressed the balloon and reduced its volume. When the pressure had increased to 70.0 atm, what was the volume of the sample? Assume that the temperature was held constant. L V = 41.9

2. A sample of vapor weighing 0.368 g filled a Florence flask when heated in a water bath at 95.0°C. The actual volume of the flask was 128.4 mL and the barometric pressure was 747 torr. Calculate (a) the volume of the vapor at STP and (b) the molar mass of the volatile liquid. (Use the approach applied in the Introduction and on the data sheet.)
What is the temperature in K of 0.500 mole of neon in a 2.00L vessel at 4.32 bar? R = 0.08314 L· bar/mol·K.
Consider the following situation: You have a 50 L tank of compressed air at 15 atm and 100 ºC. You then pass the compressed air through a "titanium getter" which contains fragments of hot titanium metal. The purpose of the "getter" is to remove oxygen gas from the sample as Ti reacts with oxygen to form solid TiO2 (known as titania). Once the purified air is passed through the getter is it cooled back down to 100 ºC and fills another 50 L storage tank. If air typically contains about 20% oxygen, what could the pressure in the storage tank be? Question 2 options: A) 12 atm B) 15 atm C) 18 atm D) 24 atm
For many purposes we can treat ammonia (NH3) a as an ideal gas at temperatures above its boiling point of -33. °C. 3 Suppose the pressure on a 1.0 m sample of ammonia gas at -2.00°C is reduced to one-third its initial value. Is it possible to change the temperature of the ammonia at the same time such that the volume of the gas doesn't change? If you answered yes, calculate the new temperature of the gas. Round your answer to the nearest °C. yes no °C x10 S
