The required mole amount of Oxygen to produce 7 .38 mole Fe 2 O 3 has to be calculated. Concept introduction: Mole: Number of atoms present in gram atomic mass of element is known as Avogadro number. Avogadro number is 6.022136 × 10 23 One mole equal of atom equal to Avogadro number ( 6.022136 × 10 23 ) hence, 1 mole of Iron contain atom 6.022136 × 10 23 Fe atoms. The mole of taken gram mass of compound is given by ratio between taken mass of compound and molar mass of compound. Mole = Mass Molar mass

Chapter 3, Problem 3.81QP
Interpretation Introduction

Interpretation:

The required mole amount of Oxygen to produce 7.38moleFe2O3 has to be calculated.

Concept introduction:

Mole:

Number of atoms present in gram atomic mass of element is known as Avogadro number.

Avogadro number is 6.022136×1023

One mole equal of atom equal to Avogadro number (6.022136×1023) hence, 1 mole of Iron contain atom 6.022136×1023 Fe atoms.

The mole of taken gram mass of compound is given by ratio between taken mass of compound and molar mass of compound.
