An average pair of lungs has a volume of 5.5 L. If the air they contain is 21% oxygen, how many molecules of o2 do the lungs contain at 1.1 atm and 37 degrees Celsius

A fuel cylinder for a camping stove contains 5.6 oz butane (C4H10), which produces 67.3 L of butane gas at 25 °C and 1.00 atm, if all of the butane in the fuel cylinder undergoes complete combustion. What volume of oxygen gas at 25 °C and 1.00 atm is needed to react with this amount of butane? L What volume of carbon dioxide gas at 25 °C and 1.00 atm is produced by this amount of butane? Question #7

A sample of nitrous oxide gas, N2O, occupies a volume of 464 L at a pressure of 0.240 atm. What volume will the gas occupy if the pressure is increased to 5.78 atm?

Helium occupies 6.82 L at 19 oC with a pressure of 954 mmHg. At what temperature will this helium takes up 8.50 L with a pressure of 795 mmHg?

If a 1.00 L container was rated to withstand pressures up to 25.0 atm, calculate what the temperature (in oC) must have been when it ruptured. The final volume of the gas at 1.00 atm and 25 oC was 15.3 L

A sample of neon gas occupies a volume of 750 ml at 25°C. What will the gas occupy at 50°C if the pressure remains constant?

What mass of chlorine gas is contained in 87.6 m3 at 290 K and 2.40 atm?  (Hint: 1 m3 = 1000. L.)

Oxygen gas can be obtained by the thermal decomposition of mercuric oxide;2 HgO(s) + heat → 2 Hg(l) + O 2(g)How many grams of HgO must be decomposed to produce 0.6433 L, measured at 9.426 °C and 1.081 atm?

A mixture of helium and methane gases, at a total pressure of 912 mm Hg, contains 0.766 grams of helium and 1.02 grams of methane. What is the partial pressure of each gas in the mixture?

The gas of a certain volcano had the following composition in mole percent: 60.0% CO2, 28.0% H2, 7.40% HCl, 1.80% HF, 2.70% SO2, and 0.100% H2S.  What would be the partial pressure of  HF in atmospheres if the total pressure was 285 mmHg? 1atm = 760mmHg
