Chapter 7, Problem 7.67P

Interpretation Introduction

(a)

Interpretation:

The volume of 4.2mol Ar needs to be determined at STP.

Concept Introduction:

The ideal gas equation is represented as follows:

  $PV=nRT$

Here, n is number of moles, P is pressure, V is volume, R is Universal gas constant and T is temperature.

In the STP condition the volume occupied by one mole gas = 22.4L

The conversion factor $=\frac{\text{1mol}}{\text{22}\text{.4L}}$

Interpretation Introduction

(b)

Interpretation:

The volume of 3.5g CO₂ needs to be determined at STP.

Concept Introduction:

The ideal gas equation is represented as follows:

  $PV=nRT$

Here, n is number of moles, P is pressure, V is volume, R is Universal gas constant and T is temperature.

In the STP condition the volume occupied by one mole gas = 22.4L.

The conversion factor $=\frac{\text{1mol}}{\text{22}\text{.4L}}$

Interpretation Introduction

(c)
