Chapter 5, Problem 5.114PAE

Interpretation Introduction

Interpretation: To determine the molecular formula of the compound.

Concept introduction:

Molecular formula tells about the total number of each type of atoms present in the compound and empirical formula is the simplest ratio of elements present in the compound.

An ideal gas which is known as the perfect gas is a gas whose volume V, Pressure P and temperature T are related through the ideal gas

$\text{PV = nRT}$

Here,

n = number of moles of the gas

R = ideal gas constant

T = Temperature

P = Pressure

Given:

Gaseous chlorofluorocarbon ${\text{C}}_{\text{x}}{\text{Cl}}_{\text{y}}{\text{F}}_{\text{z}}$ contains:$\begin{array}{l}\text{C=11}\text{.79\%}\\ \text{Cl=69}\text{.57\%}\end{array}$

$0.107\text{ g}$ of this compound fills a $458\text{ mL}$ flask at $25\text{ °C}$ having pressure of $21.3\text{ mm}\text{Hg}$
