If you don't reply with an actual answer i will report it and you will be reported and itll give me back my points 1.if i have 4 moles of a gas at a pressure of 5.6 atm and a volume of 12 liters, what is the temperature? 2.if i have an unknown quantity of gas at a pressure of 121.6 kpa, a volume of 31 liters, and a temperature of 87 0c, how many moles of gas do i have? 3.if i contain 3 moles of gas in a container with a volume of 60 liters and at a temperature of 400 k, what is the pressure inside the container? 4.if i have 7.7 moles of gas at a pressure of 0.09 atm and at a temperature of 56 0c, what is the volume of the container that the gas is in? 5.if i have 17 moles of gas at a temperature of 67 0c, and a volume of 88.89 liters, what is the pressure of the gas? use dalton’s law of partial pressures and grahams law of effusion to solve the following problems: 6.at a certain temperature, molecules of methane gas, ch4 have an average velocity of 0.098 m/s. what is the average velocity of carbon dioxide molecules at this same temperature? 7.7.) find the relative rate of diffusion for the gases chlorine, cl2 and ethane, c2h6. 8.495 cm3 of oxygen gas and 877 cm3 of nitrogen gas, both at 25.0 °c and 114.7 kpa, are injected into an evacuated 536 cm3 flask. find the total pressure in the flask, assuming the temperature remains constant.
