A container of gas holds 0.74 moles of neon gas. If the volume of the container is 11.8 liters and the pressure inside is 1.97 atm, what is the temperature (in K) of the gas?

At standard temperature and pressure, a gas has a density of 0.085 kg/m3.  What volume (in m3) does 1.03 kg of hydrogen occupy at standard temperature and pressure

A mass m of helium gas is contained in a container of constant volume V, with a pressure P and absolute (Kelvin) temperature T at the start. More helium is added, increasing the total mass of helium gas to 3 m. The temperature is found to be 2T after this addition. In terms of the initial pressure P, what is the final gas pressure?

A sealed  29.0-m3 tank is filled with  2,474 moles of oxygen gas (O2) at an initial temperature of 270 K. The gas is heated to a final temperature of  487 K. The ATOMIC mass of oxygen is 16.0 g/mol, and the ideal gas constant is R = 8.314 J/mol · K = 8.314 J/mol · K. The final pressure of the gas in kiloPascals is closest to

n = 3.9 moles of an ideal gas are pumped into a chamber of volume V = 0.125 m3.  Part (a)  The initial pressure of the gas is 1 atm. What is the initial temperature (in K) of the gas?  Part (b)  The pressure of the gas is increased to 10 atm. Now what is the temperature (in K) of the gas?

Suppose a 22.5°C car tire contains 3.85 mol of gas in a 32.5 L volume. What is the gauge pressure, in atmospheres, in the car tire? Pg1 = What will the gauge pressure be if you add a quantity of gas that had a volume of 2.00 L when it was at atmospheric pressure and the same temperature as the tire? Pg.2

A rigid tank contains 2500L of argon gas. The pressure is 3790k Pa and the temperature is 25 Celsius. How many moles of Argon are in the tank?

You are inflating the tires on your bicycle using a manual pump. The volume inside of the pump is initially 0.16 m cube with a pressure of 2 atm. If you push down on the piston and reduce the volume inside to 0.07 m cube, what is the new pressure inside of the pump? Assume the temperature inside the pump stays constant.

A gas molecule with a molecular mass of 44u has a speed of 337 m/s. What is the temperature of the gas molecule? O 6.0 x 104 K O2.0 x 104 K O 2.0 x 105 K O 2.0 x 10² K O 6.0 x 10² K

A hot air balloon uses the principle of buoyancy to create lift. By making the air inside the balloon less dense then the surrounding air, the balloon is able to lift objects many times its own weight. A large hot air balloon has a maximum balloon volume of 2090 m3   a. What is the density of air inside the balloon, in terms of the pressure P, temperature T, molar mass M, and the gas constant R?  b. How much mass can this balloon lift (in addition to the mass of the gas inside) in terms the balloon volume Vb, the atmosphere air density ρa, the density of the air in the balloon ρg, and the gravitational acceleration g?  c.  If the air temperature in the balloon is 54 °C, how much additional mass, in kilograms, can the balloon lift? Assume the molar mass of air is 28.97 g/mol, the air density is 1.20 kg/m3, and the air pressure is 1 atm.
