Chapter 11, Problem 11.106AQAP

Interpretation Introduction

Interpretation:

“The total pressure in $\mathrm{mmHg}$” should be calculated

Concept Introduction:

Here we will use the concept of Dalton’s Law of partial pressure.

► It states that the total pressure exerted by a mixture of gases is equal to the sum of the partial pressures of various gases.

$P_{total}=P_1+P_2+\mathrm{......}+P_n$

► The partial pressure is defined as the pressure that the gas would exert if it were alone in the container.

Given:

Partial pressure of argon, ${\text{P}}_{\text{Ar}}$ $\text{= 0}\text{.25}\text{atm }$

Partial pressure of helium, ${\text{P}}_{\text{He}}\text{= 350}\text{mmHg}$

Partial pressure of nitrogen,${\text{P}}_{{\text{N}}_{\text{2}}}\text{=360}\text{torr}$
