Answer:
A gas occupies a volume of 473 ml at 36.0°C. What will the new volume of the gas be ... If the initial pressure of the gas was 200. kPa what was the initial temperature? ... 6. 65 liters of a gas at a pressure of 0.80 atm is to be expanded to a new ... new pressure be if its temperature is changed to 50° Cognd its volume to 400.
Explanation:
I hope I help :)
This problem can be solved by Dalton's law of partial pressures which states that <em>in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of the individual gases</em>.
Ptotal = P₁ + P₂ + P₃ + ..... + Pn
Herein, Ptotal = P(Ne) + P(Ar) + P(He)
Ptotal = 1.25 atm, P(Ne) = 0.68 atm and P(Ar) = 0.35
So, P(He) = Ptotal - P(Ne) - P(Ar) = 1.25 - 0.68 - 0.35 = 0.22 atm
