Chapter 12, Problem 45PE

(a)

Interpretation Introduction

Interpretation:

Density of $\text{He}$ gas at STP has to be determined.

Concept Introduction:

Density of gas represents mass of gas present in unit volume. Expression of density is as follows:

  $d\left(\text{g/L}\right)=\frac{\text{mass}\left(\text{g}\right)}{\text{volume}\left(\text{L}\right)}$

Here, $d$ is density of gas.

(b)

Interpretation Introduction

Interpretation:

Density of $\text{HF}$ gas at STP has to be determined.

Concept Introduction:

Refer to part (a).

(c)

Interpretation Introduction

Interpretation:

Density of ${\text{C}}_3{\text{H}}_6$ gas at STP has to be determined.

Concept Introduction:

Refer to part (a).

(d)

Interpretation Introduction

Interpretation:

Density of ${\text{CCI}}_{\text{2}}{\text{F}}_{\text{2}}$ gas at STP has to be determined.

Concept Introduction:

Refer to part (a).
