Chapter 9, Problem 4QAP

Interpretation Introduction

(a)

Interpretation:

The mass of camphor (in mg) sublimed under the given conditions is to be calculated.

Concept introduction:

The ideal gas equation is the expression that relates different measurement properties of a gas.

The expression is given as:

$PV=nRT$

Where,

P = Pressure of the gas

V = Volume of the container in which the gas is occupied

n = number of moles of the gas ( $Numberofmoles=\frac{Givenmass}{Molecularmass}$)

R = Ideal gas constant = 0.0821 L atm/ mol K

T = Absolute temperature of the gas i.e., temperature on Kelvin scale

Interpretation Introduction

(b)

Interpretation:

The pressure in the flask due to the presence of camphor under the given conditions is to be calculated.
