Chapter 11.2, Problem 1PPC

Interpretation Introduction

Interpretation:

The diagram which best represents for fast moving gas has to be determined.

Concept introduction:

The molar mass calculated by below the formula

$\begin{array}{l}\text{molar mass of compound= }\frac{\text{mass of compound}}{\text{moles of compound}}\hfill \\ \hfill \end{array}$

Root mean-square speed is the parameter to measure the speed of particles in a gas. M is the molecular mass of the molecule at temperature T, root mean-square speed (${\text{u}}_{\text{rms}}$) has to be calculate using the formula

${\text{u}}_{\text{rms}}\text{=}\sqrt{\frac{\text{3RT}}{\text{M}}}$
