Chapter 3, Problem 3B.9E

(a)

Interpretation Introduction

Interpretation:

Final pressure of krypton in vessel has to be calculated.

Concept Introduction:

Pressure and volume of the gas are related by Boyle's law which states that at constant $T$ and $n$, volume of the gas is inversely proportional to the pressure of the system when moles of gas are constant. It is indicated as follows:

  $P\propto \frac{\text{1}}{V}$

Or

  $PV=k$

Here,

$V$ is volume occupied by the gas.

$P$ is the pressure of the gas.

$k$ is a constant.

(b)

Interpretation Introduction

Interpretation:

Final pressure of oxygen in vessel has to be calculated.

Concept Introduction:

Refer to part (a).
