- The barometric pressure is about half the sea-level value of 760 mm Hg at an altitude of 4,000-5,000 feet 9,000-10,000 feet 14,000-15000 feet 18,000-19,000 feetarrow_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 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_forward
- An aerosol spray can of deodorant with a volume of 350 mL contains 3.2 g of propane gas (C3H8) as propellant. What is the pressure (in Pa) in the can at 20 °C?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_forwardThe 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_forward

Mention three examplesarrow_forwardHow many moles of chlorine gas at 120. °C and 33.3 atm would occupy a vessel of 39.0 L?arrow_forward
- Heliox is a helium‑oxygen mixture that may be used in scuba tanks for divers working at great depths. It is also used medically as a breathing treatment. A 5.25 L tank holds helium gas at a pressure of 1734 psi. A second 5.25 L tank holds oxygen at a pressure of 461.0 psi. The two gases are mixed in a 5.25 L tank. If the temperature remains the same throughout the process, what is the pressure of the gas mixture in the tank? Assume ideal gas behavior.arrow_forwardIf a liter of a cough syrup weighs 1285g, what is the specific gravity?arrow_forwardHow many cm are in a meterarrow_forward
