Chapter 5, Problem 5.47QP

(a)

Interpretation Introduction

Interpretation:

The density of the given gas has to be calculated.

Concept Introduction:

Ideal gas is the most usually used form of the ideal gas equation, which describes the relationship among the four variables $\text{P, V, n, and T}\text{.}$  An ideal gas is a hypothetical sample of gas whose pressure-volume-temperature behavior is predicted accurately by the ideal gas equation.

$\text{Density}\text{=}\frac{\text{mass}}{\text{volume}}$

(b)

Interpretation Introduction

Interpretation:

The molar mass of the given gas has to be calculated.

Ideal gas is the most usually used form of the ideal gas equation, which describes the relationship among the four variables $\text{P, V, n, and T}\text{.}$  An ideal gas is a hypothetical sample of gas whose pressure-volume-temperature behavior is predicted accurately by the ideal gas equation.

The molar mass can be calculated from the ideal gas equation.

$\begin{array}{l}\text{molar mass}\text{= }\frac{\text{dRT}}{\text{P}}\hfill \\ \hfill \end{array}$
