Chapter 8, Problem 8.91AQAP

Interpretation Introduction

Interpretation:

“The partial pressure of ${\text{N}}_{\text{2}}$ added to the mixture” 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 oxygen, ${\text{P}}_{{\text{O}}_{\text{2}}}$$\text{= 0}\text{.60}\text{atm}$

Partial pressure of argon, ${\text{P}}_{\text{Ar}}\text{= 425}\text{mmHg }$

Total pressure after addition of nitrogen, ${\text{P}}_{\text{total}\text{after}\text{adding}{\text{N}}_{\text{2}}}\text{=1250}\text{torr}$
