Chapter 8, Problem 8.106CP

Interpretation Introduction

Interpretation:

The number of moles in $\text{14}\text{.7}\text{L}$ sample of gas at a temperature of $\text{25°}\text{C}$ and a pressure of $\text{745}\text{mm}\text{Hg}$ and the molar mass of the gas should be determined.

Concept Introduction:

Ideal gas Equation:

$\text{PV = nRT}$

Where,

$\begin{array}{l}\text{n = moles}\text{of}\text{gas}\\ \text{P = pressure}\\ \text{T = temperature}\\ \text{R = gas }\text{constant}\end{array}$

Molar mass:

$\text{Molar}\text{mass}\text{=}\frac{\text{mass}}{\text{Number}\text{of}\text{moles}}$
