- 3) An ideal gas with a volume of .867 m3 has a temperature of 119°C. If there are 8.72 x 1024 particles, what is the pressure? Hint: make sure to convert particles to moles!f 3.93 m3 of a gas initially at STP is placed under a pressure of 3.69 atm , the temperature of the gas rises to 35.2 ∘C.Answer both or none - 0.52 mol of argon gas is admitted to an evacuated 3.00 liter (3.00 × 10-3 m3) container at 20.0°C. What is the pressure of the gas, in atm? 1.00 atm = 1.00×105 Pa. 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.

- 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.The gas constant R has the value 287 J/Kg * K for dry air. Using the ideal gas law (P = PanyRT): a) Find the density of dry air at 72.05 "F with a pressure of 1095 mb. b.) Find the density of molst air at the same pressure and temperature if the relative humidity is 60%. HINT: (for o) stick with Si units (for b) Find e, given T(see lecture slides). Find e given RH.
