Gas cylinder A has a volume of 49.2 LL and contains N2(g)N2(g) at 8.26 atmatm at 25∘C∘C. Gas cylinder B, of unknown volume, contains He(g)He(g) at 9.48 atmatm and 25∘C∘C. When the two cylinders are connected and the gases mixed, the pressure in each cylinder becomes 8.75 atmatm . Part A What is the volume of cylinder B?

8. If you have a 3.0 L cylinder of compressed air that contains 2.0 g of O2, and 8.0 g of N2, then at room temperature (assume 298 K), what would be the total pressure in the tank (in atm), and the pressures of O2, and of N2 (also in atm) separately? 1. A guage on a compressed gas cylinder in a hospital reads 2.200 E3 psi (pounds per square inch). (1.00 atm = 14.7 psi). Express this pressure in...

A cylinder of monatomic ideal gas is sealed in a cylinder by a piston. Initially, the gas occupies a volume of 2.50 L and the pressure is initially 125 kPa. The cylinder is placed in an oven that maintains the temperature at a constant value. 80.0 J of work is then done on the piston, compressing the gas (in other words, the gas does -80 J of work). The work is done very slowly so that the gas maintains a...

11. A gas cylinder contains 35.0 L of nitrogen gas at a temperature of 24.6°C and a pressure of 1.95 atm. How many moles of nitrogen gas are in the cylinder? 12. How much faster does He gas diffuse than N2 gas? Assume their temperature is constant.

2. A rigid tank contains 200 moles of N2 gas at 20 °C and 2.0 atm. Using the ideal gas law, calculate the amount of gas in tank and its pressure (in bar) after each of the following steps: a) An amount of N2 equal to 1 m3 at standard conditions is withdrawn from the tank isothermally. b) The tank is heated to 75 °C. c) 40 moles of CO2, which also behaves ideally, is added to the tank and...

A sealed cylinder has a piston and contains 7.40×103 cm3 of an ideal gas at a pressure of 8.00 atm. Heat is slowly introduced, and the gas isothermally expands to 1.60×104 cm3. How much work ? does the gas do on the piston?
A mixture of methane gas, CH4(g), and pentane gas, C5H12(g), has a pressure of 0.5427 atm...
A mixture of methane gas, CH4(g), and pentane gas, C5H12(g), has a pressure of 0.5427 atm when placed in a sealed container. The complete combustion of the mixture to carbon dioxide gas, CO2(g), and water vapor, H2O(g), was achieved by adding exactly enough oxygen gas, O2(g), to the container. The pressure of the product mixture in the sealed container is 2.417 atm. Calculate the mole fraction of methane in the initial mixture assuming the temperature and volume remain constant.

The solubility of N2 in blood at 37°C and at a partial pressure of 0.80 atm is 5.6 x 10 mol/L. A deep- sea diver breathes compressed air with the partial pressure of N2 equal to 3.6 atm. Assume that the total volume of blood in the body is 4.7 L. Calculate the amount of N2 gas released (in liters at 37°C and 1.00 atm) when the diver returns to the surface of the water, where the partial pressure of...

A cylinder filled with ideal gas is sealed by a piston that is
above the gas. The piston is a cylindrical object, with a weight of
45.0 N, that can slide up or down in the cylinder without friction.
The area of the top (or the bottom) of the piston is 100
cm.
The top of the piston is exposed to the atmosphere, and the
atmospheric pressure is 100 kPa. As shown in the figure, the piston
is tied to...
