(A) What will be the total gas pressure, in bar, if 12.5 g Ne is added to the mixture of gases described in Example 6-11 and the temperature is then raised to 55 °C?

(B) 2.0 L of O₂(g) and 8.0 L of N₂(g), each at 0.00 °C and 1.00 atm, are mixed together. The nonreactive gaseous mixture is compressed to occupy 2.0 L at 298 K. What is the pressure exerted by this mixture?

Example 6-11

What is the pressure, in bar, exerted by a mixture of 1.0 g H₂ and 5.00 g He when the mixture is confined to a volume of 5.0 L at 20 °C?
