The volume of the air in the tank at
Concept Introduction:
Different laws have been put forward to introduce properties of gases:
Boyle’s law:
At fixed temperature, the volume of a fixed amount of gas is inversely proportional to the pressure exerted by the gas.
Charles’s law: States that volume is directly proportional to temperature when the gas is held
at constant pressure and number of molecules.

- The vapour pressure of water at blood temperature is 47 Torr. What is the partial pressure of dry air in our lungs when the total pressure is 760 Torr?arrow_forwardDetermine and report the pressure of collected hydrogen gas in atmospheres. Report this result to one more digit than allowed by applying the rules of significant figures. (1 atm = 760 mm Hg, an exact conversion factor.) Determine the moles of hydrogen collected by substituting the appropriate quantities into the ideal gas equation and solving. Report this result to one more digit than allowed by applying the rules of significant figures. Notes: the gas temperature is the same as the listed temperature; R = 0.082057 L-atm/mol-K. Be mindful of units. Determine the experimental atomic mass of Cu. Round this result to the correct number of significant figures. Determine the percent relative error (= ????????????−?h????????? ? 100). The molar mass of Cu is 63.546 g/mol. Mass of copper before electrolysis 6.008 g Mass of copper after electrolysis 5.860 g Volume of H2 collected 58.9 mL Pressure of H2, PH2 720.8 mm Hg Temperature 24.0 oCarrow_forwardA balloon occupies a volume of 1.25 L at sea level where the ambient pressure is 1 atm. What volume would the balloon occupy at an altitude of 10,700 m, where the air pressure is only 220 mmHg?arrow_forward
- A mouse is placed in a sealed chamber with air at 754.0 torr. This chamber is equipped with enough solid KOH to absorb any CO2 and H2O produced by the mouse. The gas volume in this chamber is measured to be exactly 2.00 L, the temperature is held constant at 295 K. After two hours the pressure inside the bottle falls to 717.4 torr. What mass of oxygen has the mouse consumed?arrow_forwardA quantity of gas in a piston cylinder had a volume of 0.539 m^3 and a pressure of 200 Pa. the piston compresses the gas to 0.222 m^3 in an isothermal (constant-temperature) process. What is the final pressure of the gas?arrow_forwardA cylinder of gas at room temperature (20 degrees Celsius) has a pressure P1. To what temperature in degrees Celsius would the temperature have to be increased for the pressure to be 1.2p1?arrow_forward
- 15.0 L of an ideal gas at 298 K and 3.36 atm are heated to 383 K with a new pressure of 6.05 atm. What is the new volume in liters?arrow_forwardA 40.0L balloon is filled with air at sea level (1.00 atm, 25.0°C). It is tied to a rock and thrown in a cold body of water, and it sinks to the point where the temperature is 4.0°C and the pressure is 11.0 atm. What will its new volume be?arrow_forwardIf 18.0 g of O2 gas has a temperature of 350 K and a pressure of 550 mmHg, what is its volume?arrow_forward
- According to Dalton’s law, what is the partial pressure of amixture of gases? What is water vapor pressure?arrow_forwardI took my basketball with 6 liters of air at 3 ATM and went deep sea diving with it. At70 meters, the intense water pressure crushed my ball, and now there are only 2.25 liters in the ball. What is the pressure at my new depth?arrow_forwardThe oxygen cost of running on a flat surface at 200 m/min would be about: (hint: pay close attention to units in each answer choice). O 30 ml. kg-1 min-1 50 ml kg-1 min-1 12.42 METS 10.96 METSarrow_forward
