Chapter 8, Problem 17QRT

Interpretation Introduction

Interpretation:

Volume occupied by $129.3\text{ g}$ gas sample has to be calculated.

Concept Introduction:

Avogadro’s Law: States that volume (V) is directly proportional to number of molecules (n) when the gas is held at constant pressure and temperature (T).

  $\begin{array}{c}\text{V}\propto \text{n}\\ \\ \text{V}\text{=}\text{Constant}\text{×}\text{n}\\ \\ \frac{{\text{V}}_{\text{1}}}{{\text{n}}_{\text{1}}}\text{=}\frac{{\text{V}}_{\text{2}}}{{\text{n}}_{\text{2}}}\end{array}$

Molar mass:

  $\text{Number}\text{of}\text{moles},\text{ n}\text{ =}\frac{\text{mass}\left(m\right)}{\text{Molar}\text{mass}\left(M\right)}$
