Chapter 7.4, Problem 7.7PP

Interpretation Introduction

(a)

Interpretation:

The volume occupied by 4.5 mol of

  $O_2$ at STP is to be calculated.

Concept Introduction:

• Ideal gas law-This law relates the pressure (P), volume(V) and the temperature(T) of the ideal gas as -

  $PV=nRT$

Where n is the number of moles of the ideal gas.

And R is the universal gas constant.

• stands for standard conditions for temperature and pressure and is defined as a temperature of 273.15 K and absolute pressure of 101.325 KPa or 1.00 atm.

Interpretation Introduction

(b)

Interpretation:

The volume occupied by 0.35 mol of $O_2$ at STP is to be calculated.

Concept Introduction:

• Ideal gas law-This law relates the pressure (P), volume(V) and the temperature(T) of the ideal gas as -

  $PV=nRT$

Where n is the number of moles of the ideal gas.

And R is the universal gas constant.

• stands for standard conditions for temperature and pressure and is defined as a temperature of 273.15 K and absolute pressure of 101.325 KPa or 1.00 atm.

Interpretation Introduction

(c)
