Problem
A 15.0 L steel tank at 350 K contains a mixture of three ideal gases whose masses are listed below.
• 4.50 g H₂(g)
• 28.0 g N₂(g)
• 44.0 g CO₂(g)
(a) Convert each listed mass to the corresponding number of moles.
(b) Determine the mole fraction of each gas in the mixture.
(c) The total pressure inside the tank is measured to be 7.85 atm. Calculate the partial pressure of N₂(g).
(d) Identify which gas exerts the greatest partial pressure and explain why, referencing your calculations.
