An auditorium has dimensions 10.0 m × 20.0 m × 30.0 m. How many molecules of air fill the auditorium at 20.0°C and a pressure of 101 kPa (1.00 atm)?

Four closed tanks, A, B, C, and D, each contain an ideal gas. The table gives the absolute pressure and volume of the gas in each tank. In each case, there is 0.19 mol of gas. Using this number and the data in the table, compute the temperature of the gas in each tank. Absolute pressure (Pa) Volume (m³) A 25.0 4.0 B 30.0 5.0 C 20.0 5.0 D 2.0 75

I need help with this question

Suppose you have a closed rigid container of air at 20 Celsius on the surface of the Earth. We change  the temperature of the container to 48 Celsius, leaving it closed, and read a pressure gauge attached to the container.  Initially the reading was 101 KPa (kilopascals, or 1000 N/m2).  What is the new reading? Give your answer in KPa.

15.01 A cylindrical tank has a tight-fitting piston that allows the volume of the tank to be changed. The tank originally contains 0.100 m3m3 of air at a pressure of 3.10 atm. The piston is slowly pulled out until the volume of the gas is increased to 0.390 m3 . If the temperature remains constant, what is the final value of the pressure? Express your answer in atmospheres.

If 23.5 moles of an ideal gas occupies 0.0465 cubic meters at 14.5 °C, what is the pressure of the gas? pressure: Pa

A rigid tank contains an amount of argon at a pressure of 12.2 atm and a temperature of 23.0°C. Two-thirds of the gas is withdrawn from the tank, while the temperature of the remainder is raised to 36.8°C. What is the new pressure (in atm) of the gas remaining in the tank? atm

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.  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.

A fixed amount of a particular ideal gas at 20°C and a pressure of 1.75 × 105 Pa occupies a volume of 2.60 m3. If the volume is increased to 4.2 m³ and the temperature is raised to 27.0°C, what will be the new pressure (in Pa) of the gas? Pa

0.52 mol of argon gas is admitted to an evacuated 3.00 liter (3.00 × 10-3 m3) container at 20.0°C. The gas then undergoes an isobaric process to a temperature of 260°C. What is the final pressure of the gas, in atm? Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
