How many grams of helium were added to the cylinder if the volume was changed from2.00to 2.50? (The temperature was held constant.)5- At 4.00, an expandable vessel contains 0.864of oxygen gas. How many liters ofoxygen gas must be added at constant temperature and pressure if you need a total of 1.84oxygen gas in the vessel?of6- which of the following relationships are correct according to Boyle’s law?1234567-A certain gas is present in a 11.04.0, andcylinder at 2.0the volume of the gas decreases to 5.5, the final value of. Find the two constants, the initial value of, to verify whether the gas obeys Boyle’s law.8-If a certain gas occupies a volume of 20when the applied pressure is 10pressure when the gas occupies a volume of 5.0, find the.9- How many air molecules are in apressure of 1.00pressure. If the pressure is increased to, a room temperature of 20.0room? Assume atmospheric, and ideal behavior.10- Imagine that you have a 7.00 gas tank and a 3.00 gas tank. You need to fill one tank withoxygen and the other with acetylene to use in conjunction with your welding torch. If you fill thelarger tank with oxygen to a pressure of 155, to what pressure should you fill the acetylenetank to ensure that you run out of each gas at the same time? Assume ideal behavior for all gases.11-What will the pressure inside the container become if the piston is moved to the 1.80while the temperature of the gas is kept constant?12-The gas sample has now returned to its original state of 1.00, 20.0What will the pressure become if the temperature of the gas is raised to 200.0not allowed to move?and 1.00mark.and the piston is13-The gas described in parts A and B has a mass of 1.66 grams. The sample is most likely whichmonoatomic gas?14- When heated, calcium carbonate decomposes to yield calcium oxide and carbon dioxide gasvia the reactionWhat is the mass of calcium carbonate needed to produce 57.0of carbon dioxide at STP?15- Butane,, is a component of natural gas that is used as fuel for cigarette lighters. Thebalanced equation of the complete combustion of butane isAt 1.003.80and 23, what is the volume of carbon dioxide formed by the combustion ofof butane?16- Calculate the density of oxygen,• STP, under each of the following conditions:•1.00and 35.0Express your answers numerically in grams per liter. Enter the density at STP first and separateyour answers by a comma.17-To identify a diatomic gas (), a researcher carried out the following experiment:She weighed an empty 1.7- bulb, then filled it with the gas at 1.20and 25.0and weighed it again. The difference in mass was 2.3 . Identify the gas.18- What is the partial pressure of argon,1flask is filled with 1.45, in the flask?of argon at 25same flask until the total pressure is 1.4019- What is the partial pressure of ethane,. A sample of ethane vapor is added to the., in the flask?20- In an effusion experiment, it was determined that nitrogen gas,, effused at a rate1.812 times faster than an unknown gas. What is the molar mass of the unknown gas?21- 15.0 moles of gas are in a 3.00 tank at 20.0. Calculate the difference in pressurebetween methane and an ideal gas under these conditions. The van der Waals constantsfor methane areand.23Gas()()5.460.03054.160.03732.250.04281.340.0322Based on the given van der Waals constants, arrange these hypothetical gases in order ofdecreasing strength of intermolecular forces. Assume that the gases have similar molarmasses.24-To prevent tank rupture during deep-space travel, an engineering team is studying theeffect of temperature on gases confined to small volumes. What is the pressure of 2.80of gasmeasured at 251in a 1.75-container assuming ideal behavior?25- To prevent tank rupture during deep-space travel, an engineering team is studying the effectof temperature on gases confined to small volumes.
