Students have asked these similar questions

(b) A mixture of helium, hydrogen and carbon dioxide gases are at a pressure of 1200 torr in a 4 L closed container. There are a total of 24 moles of gas molecules in the container. If the helium concentration is 2 moles/L and hydrogen concentration is 1.5 moles/L, estimate the partial pressure of carbon dioxide in atm.

Natural gas is a mixture of hydrocarbons, primarily methane (CH4) and ethane (C2H6). A typical mixture might have mole fraction of methane = 0.915 and mole fraction of ethane = 0.085. (a) What are the partial pressure of the two gases in a 14.10 L container of natural gas at 30 degrees Celcius and 1.34 atm? (b) Assuming complete combustion of both gases in the natural gas sample, what is the total mass of water formed? Hint: Write the balanced combustion chemical equation for each gas separately in the gas mixture to find the mass of water formed.

Be sure to answer all parts. At 1440.0 mmHg and 286 K, a skin diver exhales a 448-mL bubble of air that is 77.0% N2, 17.0% O2, and 6.0% CO₂ by volume. (a) What would the volume of the bubble be in mL if it were exhaled at the surface at 1.00 atm and 298 K? mL (b) How many moles of N₂ are in the bubble? mol N₂
