Question: A 2 00 L sample of O2 g was collected over water
A 2.00- L sample of O2(g) was collected over water at a total pressure of 785 torr and 25oC. When the O2(g) was dried (water vapor removed), the gas had a volume of 1.94 L at 25oC and 785 torr. Calculate the vapor pres-sure of water at 25oC.
Answer to relevant QuestionsIn a mixture of the two gases, the partial pressures of CH4(g) and O2(g) are 0.175 atm and 0.250 atm, respectively. a. What is the mole fraction of each gas in the mixture? b. If the mixture occupies a volume of 10.5 L at ...Consider two different containers, each filled with 2 moles of Ne(g). One of the containers is rigid and has constant volume. The other container is flexible (like a balloon) and is capable of changing its volume to keep the ...Metallic molybdenum can be produced from the mineral molybdenite (MoS2). The mineral is first oxidized in air to molybdenum trioxide and sulfur dioxide. Molybde-num trioxide is then reduced to metallic molybdenum using ...At elevated temperatures, sodium chlorate decomposes to produce sodium chloride and oxygen gas. A 0.8765-g sample of impure sodium chlorate was heated until the production of oxygen gas ceased. The oxygen gas collected over ...You have a gas in a container fitted with a piston and you change one of the conditions of the gas such that a change takes place, as shown below: State two distinct changes you can make to accomplish this, and explain why ...
