Concept explainers
(a)
Interpretation:
The greater pressure between the initial pressure of helium and the initial pressure of neon should be determined.
Concept Introduction:
Pressure of a given mass of gas at a particular temperature is defined as the force exerted per unit area of the walls of the container by colliding gas molecules.
(b)
Interpretation:
The diagram of the set-up after the stopcock between the two flasks opened should be drawn.
Concept Introduction:
At a given temperature and pressure, equal volumes of gases contain same number of moles of gas molecules.
(c)
Interpretation:
The final partial pressures of helium and neon in terms of their original pressures should be determined.
Concept Introduction:
The pressure exerted by one gas in a gaseous mixture when it occupies the same volume of the gas mixture is known as the partial pressure.
(d)
Interpretation:
The final pressures in terms of the original pressures of helium and neon should be determined.
Concept Introduction:
At constant temperature, volume of a given mass of gas is inversely proportional to its pressure.

- How would the use of a volatile liquid affect the measurement of a gas using open-ended manometers vs. closed-end manometers?arrow_forward93 The complete combustion of octane can be used as a model for the burning of gasoline: 2C8H18+25O216CO2+18H2O Assuming that this equation provides a reasonable model of the actual combustion process, what volume of air at 1.0 atm and 25°C must be taken into an engine to burn 1 gallon of gasoline? (The partial pressure of oxygen in air is 0.21 atm and the density of liquid octane is 0.70 g/mL.)arrow_forwardEthanol, C2H5OH, is produced industrially from ethylene, C2H4, by the following sequence of reactions: 3C2H4+2H2SO4C2H5HSO4+( C 2 H 5)2SO4C2H5HSO4+( C 2 H 5)2SO4+3H2O3C2H5OH+2H2SO4 What volume of ethylene at STP is required to produce 1.000 metric ton (1000 kg) of ethanol if the overall yield of ethanol is 90.1%?arrow_forward
- You have a gas, one of the three known phosphorus-fluorine compounds (PF3, PF3, and P2F4). To find out which, you have decided to measure its molar mass. (a) First, yon determine that the density of the gas is 5.60 g/L at a pressure of 0.971 atm and a temperature of 18.2 C. Calculate the molar mass and identify the compound. (b) To check the results from part (a), you decide to measure the molar mass based on the relative rales of effusion of the unknown gas and CO2. You find that CO2 effuses at a rate of 0.050 mol/min, whereas the unknown phosphorus fluoride effuses at a rate of 0.028 mol/min. Calculate the molar mass of the unknown gas based on these results.arrow_forwardA collapsed balloon is filled with He to a volume of 12.5 L at a pressure of 1.00 atm. Oxygen, O2, is then added so that the final volume of the balloon is 26 L with a total pressure of 1.00 atm. The temperature, which remains constant throughout, is 21.5 C. (a) What mass of He does the balloon contain? (b) What is the final partial pressure of He in the balloon? (c) What is the partial pressure of O2 in the balloon? (d) What is the mole fraction of each gas?arrow_forward
