A tank contains a mixture of helium, neon, and argon gases. If
the total pressure in the tank is
490. mmHg and the partial pressures of helium and argon are 21.5
mmHg and 10.2 mmHg, respectively, what is the partial pressure of
neon?
Homework Answers
Use Dalton’s law of partial pressure
Total pressure = p(He) + p(Ar) + p(Ne)
490 mmHg = 21.5 mmHg + 10.2 mmHg + p(Ne)
p(Ne) = 458 mmHg
Answer: 458 mmHg
