Question

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 215 mmHg and 102 mmHg, respectively, what is the partial pressure of neon?

Answer 1

Explanation:

sum of the individual partial pressures (P) is equal to the total pressure(P(total)).

P(total)=P(He)+P(Ar)+P(Ne)

490=215+102+P(Ne)

490=317+P(Ne)

P(Ne)=490-317

P(Ne)=173 mmHg

The partial pressure of neon is 173 mmHg
