- A 10.0 L container contains a certain gas at a temperature of 25.0◦C and pressure of 9.50 atm. Calculate the number of moles of gas in the container.n = 3.8 moles of an ideal gas are pumped into a chamber of volume V= (0.083 m³. The initial pressure of the gas is 1.01 × 10° Pa (about 1 atm). What is the initial temperature, in kelvin, of the gas? T = The pressure of the gas is increased ten times. Now what is the temperature, in kelvin, of the gas? T =At standard temperature and pressure, a gas has a density of 0.089 kg/m3. What volume (in m3) does 1.84 kg of hydrogen occupy at standard temperature and pressure [round your final answer to one decimal place]?
- A large cylindrical tank contains 0.760 m3 of nitrogen gas at 20.0 ∘C and 1.45×105 Pa (absolute pressure). The tank has a tight-fitting piston that allows the volume to be changed. What will be the pressure if the volume is decreased to 0.410 m3 and the temperature is increased to 159 ∘C? Express your answer in pascals.A balloon is filled with helium gas at atmospheric pressure (1 atm) until its volume is 800 m³. The helium gas is then transferred to cylinders that have a volume of 2.3 m³ at a pres- sure of 13.3 atm. Calculate the number of cylinders used. Assume that the temperature of the helium gas remains constant. (1 atm = 1.013 × 105 Pa).A container holds 0.420 m3 of oxygen at an absolute pressure of 3.80 atm. A valve is opened, allowing the gas to drive a piston, increasing the volume of the gas until the pressure drops to 1.40 atm. If the temperature remains constant, what new volume (in m') does the gas occupy? HINT m3 Need Help? Read It Watch It
